Below is the updated jquery code as per the updated question. It is working fine and tested. 

 $(document).ready(function(){
 $("#state").change(function() {
         if ($(this).val() === "WestBengal") {
            $(".otherdistricts").hide();
            $(".westbengaldistrict").show();
        }else{
           $(".otherdistricts").show();
            $(".westbengaldistrict").hide();
        }

answer to your updated question

$(document).ready(function(){
$(".westbengaldistrict").hide(); // first hide the select
$("#state").on("change",function() {
       if ($(this).val() === "WestBengal") {
          $(".otherdistricts").hide();
          $(".westbengaldistrict").show(); // show on change
      }
   });
});

You have several issues in your code. First of all, your closing brackets are wrong. You should have )}; instead of });

Your inputfield has display: none, you should remove that, because $(".enterotherstates").show(); won't let it appear, only the parent element.

Next, you don't need to iterate with each. It's easier and faster to use $(this). 

$(document).ready(function() {
    $("select").change(function() {
        if ($(this).val() === "WestBengal") {
            $(".enterotherstates").hide();
            $(".enterbengaldistricts").show();
        } else {
            $(".enterbengaldistricts").hide();
            $(".enterotherstates").show();
        }

    });
});

Optional performance advice

you could make your code faster by caching your jQuery objects and reuse them. So the browser doesn't have to search the complete HTML again and again:

$(document).ready(function() {

    var otherStates = $(".enterotherstates");
    var bengal = $(".enterbengaldistricts");

    $("select").change(function() {
        if ($(this).val() === "WestBengal") {
            otherStates.hide();
            bengal.show();
        } else {
            bengal.hide();
            otherStates.show();
        }

    });
});

$(document).ready(function () {
  $("select").change(function () {
    if ($(this).val() === "WestBengal") {
      $(".enterotherstates").hide();
      $(".enterbengaldistricts").show();
    }
    else {
      $(".enterbengaldistricts").hide();
      $(".enterotherstates").show();
    }
  });
});

Your code has error. Your code is:

$(document).ready(function())};

Change to:

$(document).ready(function()});

Since select is a form element you can right use val() method instead of $(this).attr("value") to get value.

Your closing parentheses and brackets are the other way around in your javaScript code.

Should be like this

$(document).ready(function () { code here });

But you have

$(document).ready(function () { code here )};

Try this

 <script>
      $(document).ready(function () {
        $("select").change(function () {
          $("select option:selected").each(function () {
            //enter bengal districts
            if ($(this).attr("value") == "WestBengal") {
              $(".enterotherstates").hide();
              $(".enterbengaldistricts").show();
            }
            //enter other states
            if ($(this).attr("value") == "Others") {
              $(".enterbengaldistricts").hide();
              $(".enterotherstates").show();
            }
          });
      });
    });
</script>

            });
