D Correct answer
Explanation

White-box testing (also called glass-box or clear-box) examines internal program structures, code, logic flows, and algorithms. Black-box testing treats software as a opaque box, testing only inputs and outputs without seeing internal code. The color refers to visibility - white means you can see inside, black means you cannot.
