Correct answer: Each VRF has a different set of routing and CEF tables., An interface must be associated to one VRF..
Why this is the answer
A Virtual Routing and Forwarding (VRF) instance creates separate routing domains within a single router. Each VRF maintains its own routing table, Forwarding Information Base (FIB), and Cisco Express Forwarding (CEF) table, ensuring traffic separation and preventing routing information leakage between different VRFs. This is why "Each VRF has a different set of routing and CEF tables" is correct. An interface can only belong to one VRF at a time to maintain clear traffic segregation and prevent ambiguity in forwarding decisions, making "An interface must be associated to one VRF" also correct. A customer site is typically associated with a single VRF for its traffic, not multiple. VRFs are defined on the PE (Provider Edge) router, not the P (Provider) device, and they do not share routing or CEF tables; that defeats their purpose of isolation.
