D. BFD sounds right to me. It's a great way to get that sub-second failure detection without having to rely on the slower OSPF convergence process.

I think the answer is D. BFD (Bidirectional Forwarding Detection) is a protocol designed specifically for quick failure detection, which is exactly what the question is asking for.
