This is a tricky one, but I'm going to go with D) An asymmetric cipher. The unique key aspect makes me think of public-key cryptography.

C) A stream cipher seems like the most fitting choice here. The unique key for each encoding is a key characteristic of stream ciphers.

But wouldn't a one-time pad be more secure since it uses a unique key every time?

I think the answer is B) A One-time pad. Using a unique key every time sounds like a perfect description of a one-time pad.

Yeah, One-time pad is the way to go for that kind of encryption.

I agree, using a unique key every time definitely points to a One-time pad.
