- B.
64 subnets, 1024 hosts

Correct answer: A
A Class B address has 16 host bits by default. Borrowing 6 bits for subnetting leaves 10 bits for hosts per subnet (16 - 6 = 10). The maximum number of usable hosts is 210 - 2, which equals 1022. Using legacy subnetting conventions that exclude the all-zeros and all-ones subnets, the maximum number of subnets is 26 - 2, which equals 62.
