With a class B network address, the default subnet mask is 255.255.0.0, which means there are 16 bits available for host IDs (32-16 = 16). If 6 bits are used for subnet IDs, then there are 10 bits remaining for host IDs (16-6 = 10). 
We can calculate the number of hosts per subnet as 2^10 - 2 = 1,024 - 2 = 1,022. The -2 is because the first and last IP address in each subnet are reserved for the network address and broadcast address respectively. Therefore, each subnet can have 1,022 hosts. 
So, the best choice is B.
