Correct answer: B

Explanation

The correct answer is B, 192.168.1.2, as it is within the subnet defined by the /30 mask, allowing communication with the host. Options A and C are either the host address or the broadcast address, which cannot be used for direct communication. Option D, 255.255.255.255, is a broadcast address that is not specific to this subnet.
