Explanation:

Chosen Plaintext Attack

https://en.wikipedia.org/wiki/Chosen-plaintext_attack

A chosen-plaintext attack (CPA) is an attack model for cryptanalysis which presumes that the attacker can obtain the ciphertexts for arbitrary plaintexts. The goal of the attack is to gain information that reduces the security of the encryption scheme.

Incorrect answers:

Rainbow Tables - precomputed table for caching the output of cryptographic hash functions, usually for cracking password hashes.

Transposition - swapping blocks of text.

Steganography - the practice of concealing a file, message, image, or video within another file, message, image, or video.
