I bet the answer is C. Public Key Cryptography. I mean, who even uses DPE these days? Sounds like a made-up term to me.

Hmm, I'm torn between B and C. But I'll go with C. Public Key Cryptography, it just makes more sense.

C. Public Key Cryptography (asymmetric cryptography) is the answer. I remember learning about this in my security class.

I'm going with D. DPE (dual-phased hybrid encryption). It has both public and private keys, so it's gotta be that one.
