I remember practicing a similar question where they discussed integrating data. I think option B sounds familiar since it mentions a central interface engine.
Okay, I think I can narrow this down. Stealth addresses and confidential transactions both use public key crypto, so those are out. Between ring sigs and zero-knowledge proofs, I'm guessing zero-knowledge is the answer since it has different underlying principles.
