Option c is the correct answer for the above answer.
Explanation:
The operating system behaves like the soul of the system. It is because it is used to operate the system. It is also used to operate all the activities of the system. It is also used to manage the resource and can be available on the computer as well as mobile. This is the first software which needs to install on a mobile or computer because without this no software can work on the mobile or computer.
The above question asks about the software which is used to operate the computer as well as mobile. That software is known as the Operating system. So the answer is Option c while the other is not because:-
Option 'a' states about the management which is not software.
Option b states about the Network which is also not a software.
Option d states about the application which is not used to operate the software of the system.
