A.
Random one-time pad

B.
DES with a 56-bit key

C.
AES with a 256-bit key

D.
RSA with a 1024-bit key

Explanation:
One-time pads are the only truly completely secure cryptographic implementations.
They are so secure for two reasons. First, they use a key that is as long as a plaintext message. That means
there is no pattern in the key application for an attacker to use. Also, one-time pad keys are used only once and
then discarded. So even if you could break a one-time pad cipher, that same key would never be used again,
so knowledge of the key would be useless.
