Explanation

Functional testing (A) is correct because it validates that a system behaves according to its specified requirements - verifying that data is processed correctly and that expected outputs (displays, reports) are produced. When you need to confirm "does the system do what it's supposed to do?", functional testing is the answer.

Reliability testing (B) measures how consistently and dependably a system performs over time - it's about stability and failure rates, not correctness of outputs.

Performance testing (C) evaluates speed, scalability, and resource usage under load - it tells you how fast or how well the system runs, not whether it produces the right results.

Regression testing (D) is run after changes to ensure that previously working functionality hasn't broken - it's a re-verification step, not the initial verification of requirements.

Memory tip: Think of Functional = Features working as specified. If the question mentions "requirements," "expected outputs," or "data correctness," the answer is almost always functional testing.
