To have at least 10 subnets, we need to use 4 of the network bits for the subnet. This leaves 18 bits for the host portion of the address. Therefore, the subnet mask would be /22 + 4 = /26, which gives us 2^4 or 16 subnets. B (3 bits) would only give us 2^3 or 8 subnets, so C (4 bits) is the best choice. A (2 bits) would only give us 2^2 or 4 subnets, which is not enough. D is not a valid choice as there is at least one correct answer.
