   A router receives a packet destined for 203.0.113.5. The router's routing table has the following entries: 203.0.113.0/24 via 192.0.2.1, 203.0.113.0/25 via 192.0.2.2, and 0.0.0.0/0 via 198.51.100.1. Which next-hop will the router use to forward the packet?

   • A192.0.2.2
   • B192.0.2.1
   • CLoad-balance between 192.0.2.1 and 192.0.2.2
   • D198.51.100.1
