• C. 192.168.4.128 is the network address for the third subnet (192.168.4.128/26) and cannot be assigned to a host.
• D. 192.168.4.132 is a valid host address but belongs to the third subnet (192.168.4.128/26), not the same subnet as options A and E.
• F. 192.168.4.63 is the broadcast address for the first subnet (192.168.4.0/26) and cannot be assigned to a host.
