C. The neighbor's advertised distance must be greater than the feasible distance of the current successor.

Suggested Answer: D. The neighbor's advertised distance must be equal to the feasible distance of the current successor. 🗳️
The feasible successor route is a route which has a higher metric than the successor route to reach a subnet but meets the feasibility condition and can be used in the event that the successor route goes down. This route does NOT get installed in the routing table but is kept in the topology table. The feasibility condition states that the AD from a neighbor must be less than the metric of the successor route (the feasible distance [FD]) because routing through a feasible successor when the AD > FD may cause a routing loop.
