Suggested answer: A

Explanation:

The correct answer is A, as it describes error guessing.Error guessing is an experience-based test technique that involves designing tests based on experience, defect data, or common knowledge about why software fails1.Error guessing can be used to complement other more formal test techniques by focusing on areas that are more likely to contain defects1.Option B is incorrect, as error guessing does not involve building test cases based on the various experiences of developers, architects, users, and other stakeholders on project teams, but based on the tester's own experience and knowledge1.Option C is incorrect, as error guessing is not a suitable test technique that can be used effectively in place of more formal techniques, but a supplementary technique that can be used in addition to more formal techniques1.Option D is incorrect, as error guessing is not a valid and useful white-box test technique due to its high degree of statement coverage, but an experience-based test technique that does not rely on the structure of the software1.
