Refer to the exhibit. Choose the correct configuration command set that will allow the gateway in zone BR to register with the gatekeeper in the same zone.

Explanation:
Notice that the router at zone Br is functioned as both gateway and gatekeeper and it uses the IP address of 10.2.120.1 as the zone local BR. Therefore if we want the gateway in zone BR to register with the gatekeeper in the same zone we must use 10.2.120.1 in the command:h323-gateway voip id BR ipaddr 10.2.120.1
In which, BR is the zone name defined in the zone local BR command (of the gatekeeper) and the is the IP address of an interface of the gatekeeper and it should be 10.2.120.1-> B, D and E are not correct.
A can be correct but it is not as clear as answer C.
Notice that last command h323-gateway voip h323-id BRgw specifies the BRgw is the name of the gateway to communicate with the gatekeeper.
