Answer:
Option D) 5
Explanation:
4 subnet bits is 240 mask which provides [tex]2^{4}[/tex], i.e., 16 subnets and provides 14 hosts for each.
In order to achieve the target and provide correct subnet mask, 5 subnet bits are required to be borrowed from the host of a classful network address as then the addition of one more subnet bit would result in 248 mask which in turn gives 5 subnet bits which results in [tex]2^{5}[/tex], i.e., 32 subnets and 3 host with 6 host per subnet.
