Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Environment variables in shell/operating systems come in two main types: built-in variables provided by the system (like PATH, HOME, USER) and user-defined variables created by the user. Option D correctly identifies both types. Option C is incorrect because 'User-function' is not a type of environment variable.
