        $total  = $_POST["lines"];
        $quesA  = $_POST["ques"];
        $quesNo = 1;
        $opt    = array("","A","B","C","D");

        for ($i = 0; $i < $total; $i++)
        {
            $q = $quesA[$i][0]; // here error

    ...

Here I assign $quesA = $_POST["ques"]; now it take a variable $q = $quesA[$i][0]; then print in line

echo "<div><b style='color:red;'>Q" . $quesNo . " : </b>"
     . "<span style='color:blue;'>" . $q ."</span></div>"
;

The problem is that $quesA[$i] is not a valid array and you are trying to use it like an array.

Am not sure how you are getting $_POST["ques"] but you need to make sure its an array before you can access it.

Post what you are expecting from $_POST["lines"] & $_POST["ques"]; i may be able to help further
