The Expressway-C IP is 192.168.20.10/24. The default gateway for each subnet is the first useable address. How must the Expressway-E be configured to allow proper routing to the internal and external networks?

Options :

A : IPv4 gateway: 172.16.100.1, and a static route for the 192.168.100.0/24 subnet using LAN1

B : IPv4 gateway: 192.168.100.1, and a static route for the 192.168.20.0/24 subnet using LAN1

C : IPv4 gateway: 192.168.100.1, and a static route for the 172.16.100.0/24 subnet using LAN2

D : IP v4 gateway: 172.16.100.1, and a static route for the 192.168.20.0/24 subnet using LAN1
