Which one of the following statements should be used to disable just the fopen(), and file() functions?

(a) disable_functions = fopen(), file()

(b) disable_functions = fopen, file

(c) functions_disable = fopen(), file()

(d) functions_disable = fopen, file

This question was posed to me in my homework.

My doubt stems from Website Security using PHP in division File and Session Handling in PHP of PHP
