Correct Answer: A
Explanation:
Exploratory testing can replace black box techniques when testing time is very limited, because it is a type of experience-based technique that allows testers to design and execute tests based on their intuition, knowledge, and skills, without following a predefined test plan or test cases13. The other options are false statements about testing techniques.Option B is false, because test execution scheduling should give priority to specification-based or structure-based techniques, which are more systematic and objective than experience-based techniques13.Option C is false, because specification-based techniques cannot be used as a substitute for a poorly defined test basis, but rather require a clear and complete test basis to design effective test cases13.Option D is false, because experience-based techniques are not systematic and do not produce detailed test documentation, but rather rely on the tester's judgement and creativity
