Answer:
The correct answer to the following question will be option C.
172.16.80.1-172.16.87.254
Explanation:
IP Address: IP Address stands for Internet Protocol Address, a unique numerical label allotted to every computer network that are connected to the network of the computer and communicate through the internet protocol.
- An IP address can be separated by periods and having four numbers that are called Octet. Range of IP address can be from 0 to 255.
- We have to keep the first 21 bits and start setting all from the 22nd bit on to 0 (zero).
- To get the suitable and the correct range of the address, we add and subtract 1 from the given broadcast address i.e.,172.16.85.0/21.
So, option C is the right answer and no other option is usable according to the given explanation and the address given by the administrator.

Solution:
It is done by Operating system.
An Operating system is system software that manages computer hardware and software resources and provides common services for computer programs.
Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources.
For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers.
