Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Availability
Availability ensures that systems and data are accessible when needed. The requirement to recover the database within four hours defines a Recovery Time Objective (RTO), which is an availability requirement. Therefore, Option A is correct. Option B (Integrity) ensures data accuracy and protection from unauthorized modification, not recovery time. Option C (Non-repudiation) prevents denial of actions, which is unrelated. Option D (Confidentiality) protects data from unauthorized disclosure.
