What term describes the difference between data that is secured through encryption and data that is not?

• A. Plaintext vs ciphertext
• B. Secured vs unsecured
• C. Encrypted vs unencrypted
• D. Protected vs unprotected

Answer: (C)

This question is about the state of data with respect to encryption—whether it is protected or not. When data is encrypted, it is transformed into ciphertext and becomes unreadable without the key. When data is not encrypted, it remains plaintext, which is readable. Describing the difference as encrypted vs unencrypted directly communicates whether the data is protected by encryption or not, making it the clearest choice. Plaintext vs ciphertext also reflects pre- and post-encryption states, but the question focuses on the security status, so encrypted vs unencrypted is the most direct descriptor. Terms like protected vs unprotected or secured vs unsecured are vague and less precise for this cryptographic context.
