    $ans_checked = explode(',', $answered);
    foreach ($answer_options as $a)
    {
        $checked = '';

As I see it is checking all the checkboxes for this code. Once the $checked is set with "checked" value it remains.

You should use else part to unset it if not present. Or do - 

$checked='';
if(in_array($a,$ans_checked))
{
     $checked="checked";
}

inside the loop.

Also you should do - 

$ans_checked=array_map('trim', explode(',',$answered));
