Definitely option A. The attacker selects the plaintexts and gets the corresponding ciphertexts - that's a textbook chosen plaintext attack!

I'm not sure, but I think it might be C) Known-plaintext attack, where the attacker has access to both plaintext and ciphertext pairs.

I agree with Armando, because in chosen plaintext attack, the attacker can choose the plaintexts.
