B is correct because the 10.xx.xx.xx, 172.16.xx.xx, and 192.168.xx.xx are private IP addresses. 19.0.0.0/8 is considered a public IP.

Selected Answer: B

The IP address most likely configured on the router’s WAN port is: B. 19.45.7.28 This is because the WAN port typically receives a public IP address from the ISP, which is used to identify the network on the internet1. The other options are either private IP addresses (A and D) or an APIPA address ©, which are not used for WAN configurations. -according to Copilot
