D
Correct answer
Explanation
Adhoc testing is performed without formal test plans or test case documentation. Testers rely on their intuition, experience, and understanding of the system to find defects on an ad-hoc basis. This contrasts with Alpha testing (A) which is formal testing by developers, Beta testing (B) which is formal user testing, and Unit testing (C) which follows structured test cases for individual components.
