Answers
D.
In an expert-based approach, the test lead with the most years in the role is chosen to produce the estimate.
Suggested answer: B

Explanation:

According to the syllabus, there are two main approaches for estimating test effort: metrics-based and expert-based. The metrics-based approach uses metrics from previous similar projects or industry data to calculate the test effort based on the size and complexity of the software under test. The expert-based approach relies on the experience and judgment of the owners of the testing tasks or subject matter experts who provide their estimates based on their knowledge of the software under test. The answer B is correct because it accurately describes the expert-based approach. The other answers are incorrect because they either confuse the metrics-based and expert-based approaches or describe them incorrectly.
