Please follow the below steps to achieve the required result
1. Take a variable name it maxdelcount assign the value 3 to it.
2. Take another variable delcount assign the value 0 to it.
3. Check the condition if delcount is less than maxdelcount before this line "$(this).remove()". if delcount is less than maxdelcount the remove the div and increment delcount.
4. If delcount is greater than or equal to maxdelcount then display the alert message.

Hope the above steps help

JavaScript

<script type="text/javascript">
var maxdelcount=2;
var delcount=0;
$(".form-horizontal").delegate("#removelink", "click", function () {
$(this).closest('.optiondiv').hide('slow', function(){
if (delcount < maxdelcount)
{
$(this).remove();
resequence();
delcount++;
}
else if (delcount >= maxdelcount)
{
alert("hi");
}
});

});
</script>

div C, but its coming D.

Use hidden field to keep track of how many divs are removed.

HTML

<html>
<head>
<script type="text/javascript" src="https://code.jquery.com/jquery-1.8.3.min.js"></script>
</head>
<body>
<script type="text/javascript">
$(function(){
$("#removelink").live("click", function () {
var currentVal = parseInt($("#counter").val(),10);
if(currentVal >=3) { alert("Ninja Attack - You cannot remove more than 3 divs !!!"); return;}
    $(this).closest('.o').hide('slow', function(){
        $(this).remove();

         currentVal+=1;
         $("#counter").val(currentVal);
        });
    });
});
</script>
<div class="o" >
<a href="#x" id="removelink">Remove</a></div>
<div class="o" >
<a href="#x" id="removelink">Remove</a></div>
<div class="o" >
<a href="#x" id="removelink">Remove</a></div>
<div class="o" >
<a href="#x" id="removelink">Remove</a></div>

<input type="hidden" id="counter" value="0"/>

</body>
</html
