Which command would correctly configure a serial port on a router with the last usable host address in the 192.216.32.32/29 subnet?

A.
router (config-if)# ip address 192.216.32.38 255.255.255.240

B.
router (config-if)# ip address 192.216.32.39 255.255.255.224

C.
router (config-if)# ip address 192.216.32.63 255.255.255.248

D.
router (config-if)# ip address 192.216.32.39 255.255.255.248

E.
router (config-if)# ip address 192.216.32.63 255.255.255.248

F.
router (config-if)#ip address 192.216.32.38 255.255.255.248

Explanation:
This question is to examine the IP addressing.
In the 192.216.32.32/29 subnet, the network number is 192.216.32.32.
The first usable IP address is 192.216.32.33.
The last usable IP address is 192.216.32.38.
192.216.32.39 is the broadcast address, /29 represents 255.255.255.248.
