Which IP address and wildcard mask test for hosts from an entire subnet of network 192.168.12.0 using a 29-bit mask?

• 192.168.12.56 0.0.0.15
• 192.168.12.56 0.0.0.8
• 192.168.12.56 0.0.0.31
• 192.168.12.84 0.0.0.7
• 192.168.12.84 0.0.0.3
• 192.168.12.84 0.0.0.255

Explanation: The wildcard mask can be derived by subtracting the 29-bit mask, 255.255.255.248, from 255.255.255.255. This results in the wildcard mask 0.0.0.7. 192.168.12.84 is a subnet of 192.168.12.0/29.
