Answer: B

Explanation

The set ip default next-hop command verifies the existence of the destination IP address in the routing table, and…

C If the destination IP address exists, the command does not policy route the packet, but forwards the packet based on the routing table.

C If the destination IP address does not exist, the command policy routes the packet by sending it to the specified next hop.

The set ip next-hop command verifies the existence of the next hop specified, and…

C If the next hop exists in the routing table, then the command policy routes the packet to the next hop.

C If the next hop does not exist in the routing table, the command uses the normal routing table to forward the packet.
