The correct answer is A. Asymmetric. Asymmetric encryption correctly fills the blank because it is defined by the use of a mathematically linked key pair - a public key for encryption and a private key for decryption - making it distinct from symmetric encryption, which uses a single shared key.

Explanation

Asymmetric encryption correctly fills the blank because it is defined by the use of a mathematically linked key pair - a public key for encryption and a private key for decryption - making it distinct from symmetric encryption, which uses a single shared key. The "two-key" mechanism is the defining characteristic, and "public key encryption" is the standard alias for this approach (used in TLS, RSA, and SSH). Since only one choice is provided here, there are no distractors to eliminate.

Memory tip: Think asymmetric = unequal - the two keys are different (not the same), just as asymmetry means "not matching on both sides." If you encrypt with one, you decrypt with the other - never the same key twice.
