Consider the following PHP code:

<?php
echo strlen(md5(rand(),TRUE));
?>

16
Correct: 16

Explanation: Answer option C is correct.

The md5() function is used to calculate the md5 hash of a string. The syntax of the md5 function is as follows:

string md5 ( string $str [, bool $raw_output = false ] )

Note: If the optional raw_output is set to TRUE, the md5 function returns a string having raw binary format with a length of 16 bit.

Answer options D, A, and B are incorrect. These are not valid output according to the script.
