Why each option
After encryption is applied to plaintext, the resulting scrambled output is called ciphertext.
A message digest is the fixed-size output of a hashing function applied to data, used for integrity checking, not encryption.
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.
Hash result is synonymous with message digest - it is the output of a hash function, not an encryption operation.
Fingerprint is an informal term for a hash or digest used to identify data, not the result of encrypting a message.
