c. security
d. reliability, scalability, and portability

Explanation:

To solve this, we analyze each option:

• Option A: Resilience and Redundancy focuses on system recovery and backup, not user - familiar systems.
• Option B: Interoperability is about systems working together, not about using user - familiar systems.
• Option C: Security is about protecting systems from threats, not related to user - familiar systems.
• Option D: Reliability, Scalability, and Portability includes using systems familiar to users (portability and usability - related aspects) as part of ensuring systems work well for users.

Answer:

D. Reliability, Scalability, and Portability
