Why each option

After encryption is applied to plaintext, the resulting scrambled output is called ciphertext.

Amessage digest

A message digest is the fixed-size output of a hashing function applied to data, used for integrity checking, not encryption.

BciphertextCorrect

Ciphertext is the technical term for data that has been transformed by an encryption algorithm using a key, rendering it unreadable without the corresponding decryption key. The process of converting plaintext to ciphertext is the fundamental operation of any encryption scheme.

Chash result

Hash result is synonymous with message digest - it is the output of a hash function, not an encryption operation.

Dfingerprint

Fingerprint is an informal term for a hash or digest used to identify data, not the result of encrypting a message.
