Show answer & explanation
Correct answer: B
Assertion A (Validity checks real need of system users)
True
Validity asks: “Are we building the right system?”
It ensures the system actually meets the real needs of users.Reason R (Completeness checks system user defined requirements)
True
Completeness checks whether all stated requirements have been fully specified—nothing is missing.Why R is NOT the explanation of A:
Validity and completeness are different quality attributes of requirements.
Completeness does not explain why validity checks real user needs.
Hence, both statements are true, but R does not explain A
