I'm going with C. Symmetric encryption is the OG of encryption methods. Using the same key is the whole point, not some fancy MAC or key size shenanigans.

C is the way to go. Symmetric encryption is all about having a single key that works both ways. It's like a two-way street for your data!

Hmm, I'm torn between B and C. Symmetric encryption is about the key, not the size of the ciphertext. But C seems to be the clearest answer here.

Yeah, you're right. B is not accurate because the size of the ciphertext doesn't have to be the same as the plaintext. C is the best choice.

I think C is the correct answer. Symmetric encryption uses the same key for both encryption and decryption.

I believe symmetric encryption is more secure because it uses a single key for both encryption and decryption.
