Hi Himanshu,

Greetings to you!

The SelectOption constructors signature is public SelectOption(String value, String label)

You are using 3 parameters instead of two. Please try below code, I have changed a few things in your code:
  
public class CustomerAmtTransfer {

    public String Name1 { get; set; }
    public String Name2 { get; set; }


    public List<Selectoption> getName1fields() {
    List<Selectoption> listName1 = new List<selectoption>();
    listName1.add(new selectOption('', '- None -'));
    for(Customer__c cs : [Select Id, First_Name__c, Last_Name__c from Customer__c]){
     listName1.add(new selectoption(cs.id,cs.First_Name__c));
     }
        return listName1;
    }
    public List<Selectoption> getName2fields() {
    List<Selectoption> listName2 = new List<selectoption>();
    listName2.add(new selectOption('', '- None -'));
    for(Customer__c cs : [Select Id, First_Name__c, Last_Name__c from Customer__c]){
     listName2.add(new selectoption(cs.id,cs.Last_Name__c));
     }
        return listName2;
    }
}

I hope it helps you.
