Which three components make up the CIA triad?

• A. Availability, Integrity, Confidentiality
• B. Integrity, Confidentiality, Availability
• C. Confidentiality, Availability, Integrity
• D. Confidentiality, Privacy, Non-repudiation

Answer: (C)

The CIA triad represents three fundamental goals of information security: confidentiality, integrity, and availability. Confidentiality means only authorized people can access information. Integrity ensures data remains accurate and unaltered. Availability guarantees that authorized users can access information and systems when needed. The best answer lists Confidentiality, Availability, Integrity—covering all three goals, just in a different order. That completeness is what makes it the right choice. The other options introduce terms outside this triad (like privacy or non-repudiation), which aren’t part of the standard three core objectives.
