Explanation

Cryptography is the art and science of securing information by transforming it into an unreadable format so only intended recipients can understand it - making A correct. It's fundamentally about secrecy, not publicity (B), anonymity (C), or decoding alone (D).

B is wrong because public messages require no protection - cryptography exists precisely to prevent public access.
C is wrong because anonymity concerns identity, not message content; cryptography protects the message itself.
D is wrong because decoding (breaking ciphers) is actually cryptanalysis - the opposite discipline that tries to defeat cryptography.

Memory tip: The Greek roots give it away - kryptos means "hidden" and graphia means "writing." Cryptography = hidden writing = secret messages.
