Apex Select List not showing any values

I am trying to create an apex:selectList but I am getting stumped. I think the issue resides in my controller extension. I am not a developer by any means so I am not sure what I am doing wrong.  The apex list is intended to be a multi select.
  
<apex:page standardController="Task" extensions="LogACallControllerExtension,NextStep" docType="html-5.0" showHeader="false" standardStylesheets="false">

<apex:form >     
<div class="app-content"> 
<header>
<h1>Log A Call</h1><br /><br />
</header>

<section class="border-bottom">
<div class="content">   
 <label>Next Steps</label><br />
 <apex:selectList id="NextStep" styleclass="sf1input" multiselect="true" value="{!Task.Next_Steps__c}" size="1" />
<apex:selectOptions value="{!NextStepOptions}"/>
  </div>
 </section

<section class="data-capture-buttons one-buttons">
<div class="content"><apex:commandButton value="Save" action="{!save}" /><br />
</div>
</section>
</div>
</apex:form>
</apex:page>

**---ControllerExt--** 

public with sharing class NextStep {

    public NextStep() {

    }


    public NextStep(ApexPages.StandardController controller) {

    }

        String[] NextSteps = new String[]{};
         public PageReference test() {
            return null;
        }
            
        public Task task {get; set;}
            
        public List<SelectOption> getNextStepOptions() {
            List<SelectOption> options = new List<SelectOption>();
            options.add(new SelectOption('Op1','Op1'));
            options.add(new SelectOption('Op2','Op2'));
            options.add(new SelectOption('Op3',Op3));
             options.add(new SelectOption('Op4','Op4'));
             
            return options;
        }
            
        public String[] getNextSteps() {
            return NextSteps;
        }
            
        public void setNextSteps(String[] NextSteps) {
            this.NextSteps = NextSteps;
        }
    }

Hi, below is the code

VF-Page:
Since you mentioned multiselect="true", it shows multi-select all the time. 
<apex:page standardController="Task" extensions="LogACallControllerExtension,NextStep" docType="html-5.0" showHeader="false" standardStylesheets="false">
    <apex:form >     
        <div class="app-content"> 
            <header>
                <h1>Log A Call</h1><br /><br />
            </header>
            <section class="border-bottom">
                <div class="content">   
                    <label>Next Steps</label><br />
                    <apex:selectList id="NextStep" styleclass="sf1input" multiselect="false" value="{!Task.Next_Steps__c}">
                        <apex:selectOptions value="{!NextStepOptions}"/>
                    </apex:selectList>
                </div>
            </section>
            <section class="data-capture-buttons one-buttons">
                <div class="content"><apex:commandButton value="Save" action="{!save}" /><br /></div>
            </section>
        </div>
    </apex:form>
</apex:page>

Apex-Class:
In this class, you had missed single-quotes for "Op3". 
public with sharing class NextStep {

    public NextStep() { }
    public NextStep(ApexPages.StandardController controller) { }

    String[] NextSteps = new String[]{};
     public PageReference test() {
        return null;
    }
            
    public Task task {get; set;}
        
    public List<SelectOption> getNextStepOptions() {
        List<SelectOption> options = new List<SelectOption>();
        options.add(new SelectOption('Op1','Op1'));
        options.add(new SelectOption('Op2','Op2'));
        options.add(new SelectOption('Op3','Op3'));
        options.add(new SelectOption('Op4','Op4'));         
        return options;
    }
            
    public String[] getNextSteps() {
        return NextSteps;
    }
        
    public void setNextSteps(String[] NextSteps) {
        this.NextSteps = NextSteps;
    }
}
If the above suggestion(s) worked, let us know by marking the answer as "Best Answer" right under the comment which will help the rest of the community should they have a similar issue in the future.
Thanks, Sunil

Thank you for the quick response and pointing out my errors. Two questions though.
  1. How come I can only select one value even though I set multiselect="true" ?
  2. How come it returns the value selected with brackets around it? [Op2] ?
