Which configuration on a client PC allows internet access given the router configuration?

The correct choice is based on the IP addressing requirements for a client PC to successfully access the internet through a router. For a client PC to communicate with a router and establish an internet connection, it must be within the same subnet as the router's local interface, and it must set the correct gateway IP address that corresponds to the router's local interface.

In this case, the option stating the IP of 192.168.2.115/24 and a gateway of 192.168.2.1 is appropriate. The IP address falls within the expected range of the subnet (192.168.2.0/24), and the gateway is correctly specified as 192.168.2.1, which is likely the router's local interface address. This configuration allows the client to route packets to the internet through the router effectively.

Other options either assign IP addresses that are outside the expected subnet of the router's configuration or specify incorrect gateway addresses that do not align with the router's local interface, meaning those configurations would not facilitate proper internet access.
