  C is correct, CEF is a high-speed packet forwarding mechanism that BFD relies on to quickly detect link failures. CEF must typically be enabled for BFD to function properly on Cisco devices. Without CEF, the BFD packets might have to be process-switched (handled by the CPU), which could slow down the detection of failure
