Firstly, we should know, what a Class B network is and how is it different from Class A network and Class B network.
IP Address Class Network and Host Capacities According to the formula number of subnets = 2^n
So, the subnet mask would be = 11111111.11111111.11111100.00000000
Hence, answer is 255. 255. 252. 0

Subnetting a Class B Network
When an organization has a large network, it is common to divide it into smaller subnets to improve network performance and security. Subnetting a Class B network requires dividing the network into smaller groups of IP addresses to create subnets.
Determining the Subnet Mask
To determine the subnet mask that will allow for 64 departments, we need to calculate the number of subnets and hosts per subnet.
The formula for calculating the number of subnets is 2^n, where n is the number of subnet bits. In this case, we need 64 subnets, which is 2^6. Therefore, we will need 6 subnet bits.
The formula for calculating the number of hosts per subnet is 2^n - 2, where n is the number of host bits. We do not know the number of hosts per subnet, but we know that it needs to be greater than or equal to the number of hosts in the largest department. Let's assume that the largest department has 100 hosts.
We need to find the number of host bits that will allow for at least 100 hosts per subnet. We can use the formula 2^n - 2 = H, where H is the number of hosts per subnet.
2^n - 2 = 100
2^n = 102
n = 6.64
We need at least 7 host bits to allow for 100 hosts per subnet.
Therefore, the subnet mask that will allow for 64 subnets and at least 100 hosts per subnet is 255.255.252.0, which has 6 subnet bits and 10 host bits.
Answer: D) 255.255.252.0

D)
In order to represent 64 subnets, we need 6 bits(2^6=64). Since Class B has 255.255.0.0 as default network ID, when we use 6 bits for subnet mask, then we get subnet ID as 255.255.252.0.
