A is right answer since three bits are borrowed (128+64+32) = 224.

Yes, A is the Only correct Answer.

8 subnets, 8 = 2 ^3, so the network bits(N) is = 3, so the subnet mask is = 11100000 in binary and 224 in decimal notation.

So, the correct Answer is A . 255.255.224.0.

2^n-2= subnet for eight we need 4 bits i think but 255.255.

255.255.240 is the answer.

@Sandeep.

2^n-2 is the formula of valid hosts not for the subnet, so n=3 is correct and A is a valid answer.
