What does the FILE constant contain?

The correct answer is B. The full path to the current script. __FILE__ holds the full absolute path to the currently executing script file (e.g., /var/www/html/app/index.php), not just its filename - which is why B is correct and A is wrong.

Explanation

__FILE__ holds the full absolute path to the currently executing script file (e.g., /var/www/html/app/index.php), not just its filename - which is why B is correct and A is wrong. C is incorrect because __FILE__ has nothing to do with HTTP requests; that's what $_SERVER['REQUEST_URI'] handles. D is a trap: __FILE__ always reflects the current file, even if included from another script - the "main script" would be __DIR__ . '/' . basename($_SERVER['SCRIPT_FILENAME']) or similar.

Memory tip: Think of __FILE__ like asking "where am I on disk right now?" - the answer is always a full address (path), not just your name (filename).
