Answer: Option B

Solution

Answer: Option B
Solution:
In Class B networks, the IP address space is divided into a large number of smaller networks, each with a moderate number of hosts.
A Class B network uses a 16-bit network prefix, allowing for 65,534 possible host addresses per network.
The total number of possible Class B networks is calculated as 214214, which equals 16,384 networks.
So, in summary, for a Class B network, there are 16,384 networks and 65,534 nodes per network.
