PFA screen shot 

I am trying to add a new contact record with below condition where Account has greter than  99 employees  an limit is 1.
Though new  contact is not getting created in accounts where  employess are more than 99.
let me know what is wrong in below code.
(New to apex)
Contact c = new Contact(Account = [SELECT Name FROM Account 
    WHERE NumberOfEmployees > 99 Limit 1]);
c.FirstName = 'Test';
c.LastName = 'AM';
System.debug('Contact name  is '+c);    

 ****This is my component details**** 
Attribute:
<aura:component >
    <aura:attribute name="ABC" type="string" default="false"/>

**This is lightning button details**
<lightning:button label="Submit" onclick="{!c.doSubmit}"></lightning:button>

**THis is my funtion doSubmit in controller**

({
    doSubmit : function(cmp, evt, hlpr) {
 //accessing the value in attribute ABC
        var initialABCValue = cmp.get("v.abc");
                if(initialABCValue == "true"){
                       alert("Value is true");
 //setting value of ABC to false
            cmp.set("v.abc","false");
        }
            else{
                     alert("Value is False");
 //setting value of ABC to true
            cmp.set("v.abc","true");
        }
    }
})
