Disabling checkboxes based on condition

I have 3 checkboxes say checkbox A, checkbox B, checkbox C. I have a requirement something like

1. If checkbox A is checked, then checkboxes B and C should be disabled.


2. I can check both checkboxes B and C simultaneously in which case checkbox A should be disabled.


3. Upon selecting checkbox B or Checkbox C alone (single selection), in either of the case, Checkbox A should be disabled.

Below is my code:

$("#B").change(function(){
    if($("#B").is(':checked'))
    {
      $("#A").attr("disabled", true);
    }
    else
    {
      $("#A").attr("disabled", false);
      $("#B").attr("disabled", false);
      $("#C").attr("disabled", false);
    }
  });

  $("#C").change(function(){
    if($("#C").is(':checked'))
    {
      $("#A").attr("disabled", true);
    }
    else
    {
      $("#A").attr("disabled", false);
      $("#B").attr("disabled", false);
      $("#C").attr("disabled", false);
    }
  });

  $("#A").change(function(){
    if($("#A").is(':checked'))
    {
      $("#B").attr("disabled", true);
      $("#C").attr("disabled", true);
    }
    else
    {
      $("#A").attr("disabled", false);
      $("#B").attr("disabled", false);
      $("#C").attr("disabled", false);
    }
  });

Can anyone please help me with this
