A. System Assert statements that do not increase code coverage contribute important feedback in unit tests.

• Explanation: System Assert statements are essential in unit tests as they validate the behavior and outcomes of the code being tested. Even if they do not directly increase code coverage, they ensure the correctness of the code, which is crucial for reliable software.

C. Increased test coverage requires large test classes with many lines of code in one method.

• Explanation: While this statement is partially true, it’s often more effective to have multiple, well-organized, and focused test methods rather than large test classes with many lines of code in one method. However, the statement implies a common misconception; good practice actually involves creating concise and modular test methods to ensure thorough and maintainable test coverage.
