Given the following examples of entry and exit criteria: 1. A defined level of code coverage has been achieved 2. The test automation tool has been…

Entry criteria are conditions that must be met before a testing phase can begin, while exit criteria are conditions that must be met before a testing phase can be considered complete.
- Entry Criteria: Items 2, 4, and 5 are prerequisites. Testing cannot start effectively until the tool is ready (2), the environment is available (4), and the requirements are testable (5).
- Exit Criteria: Items 1, 3, and 6 define the completion of testing. Testing is considered done when code coverage targets are met (1), the defect count is acceptably low (3), or the budget is exhausted (6).

B. This option incorrectly classifies code coverage (1) and defect limits (3) as entry criteria, and tool setup (2) and defined user stories (5) as exit criteria.
C. This option incorrectly classifies defined user stories (5) as an exit criterion; it is a prerequisite for starting testing (entry criterion).
D. This option incorrectly classifies the budget being spent (6) as an entry criterion; it is a condition for stopping testing (exit criterion).
