B, Differential cryptanalysis, seems legit. Although I'm just guessing since crypto is not my strong suit.

I'm going with C. Known-plaintext attack makes the most sense here, since the attacker has access to both the plaintexts and ciphertexts.

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.
