Symmetric encryption? More like 'same-same' encryption if you ask me. But hey, at least it's not 'asymmetric' - that would just be confusing!

D) seems like it's describing a one-time pad, which is a special case of symmetric encryption. I'm sticking with C.

B) sounds like it's just describing the concept of a block cipher, not symmetric encryption specifically. I'll go with C.

I'm pretty sure it's C. I mean, if you can't encrypt and decrypt with the same key, what's the point of calling it 'symmetric'?
