Cs
C
PHP

Python
Correct Answer: PHP
PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML. One of the lesser known sides of external JavaScript is the ability to reference a PHP file instead of the familiar .js file.
