A is the correct answer, but this won't work without fixing the encapsulation to be "encapsulation dot1q 10"

Configuring a valid ip address in Gi2 would work just fine assuming that the switch/trunk port that Gi2 is connected to has the "switchport trunk native vlan 10" command applied. Untagged "native vlan" frames are directed to the main/physical interface of the router. Of course, if on the real test the subinterface number and the vlan match then the answer would be A.

A is correct but FOR GOD SAKE!!! This will not function properly because the vlan specified in the encapsulation dot1q command is wrong. They should pay a lot more of attenction about these questions...
