In which of the following cryptography attack methods, the attacker makes a series of interactive queries, choosing subsequent plaintexts based on the information from the previous encryptions?

A chosen-plaintext attack allows the attacker to encrypt arbitrary plaintexts, but all choices are made non-adaptively without using prior encryption outputs to guide subsequent selections.

A ciphertext-only attack gives the attacker access only to ciphertexts with no ability to choose or obtain encryptions of any plaintext.

In an adaptive chosen-plaintext attack, the attacker submits plaintexts to an encryption oracle and uses the resulting ciphertexts to inform the choice of the next plaintext query. This adaptive, interactive feedback distinguishes it from a standard chosen-plaintext attack, where all plaintexts must be chosen before seeing any ciphertexts, giving the attacker a systematic method to extract key information incrementally.

A known-plaintext attack provides the attacker with a fixed set of plaintext-ciphertext pairs that were not chosen by the attacker and involve no interactive querying.
