What is an EIGRP successor for a destination network?

Question:

What is an EIGRP successor for a destination network?

• the next hop on the primary route with the smallest feasible distance to the destination
• the next hop on a backup route with the largest feasible distance to the destination
• the next hop on a backup route with the smallest feasible distance to the destination
• the next hop on the primary route with the largest feasible distance to the destination

Explanation: The successor is the first next-hop router for the successor route (primary route). A successor route is a route with the lowest-metric path to reach a destination network (feasible distance).
