A subnet mask consists of all 1's in the network part and all 0's in the host part. In binary, -14 is represented as 11110000. This means that the first 4 bits are in the network part, and the remaining 4 bits are in the host part. However, since IPv4 addresses are 32 bits long and the network part also includes the IP address itself, we subtract 32-4=28. Therefore, there are 28 bits in the host part. Option D states 18, which is incorrect. The correct answer is D, with 28 bits in the host part.
