The correct answer is option 'C': Both of the mentioned.

Explanation:
The process manager is responsible for managing and overseeing the execution of various programs in a computer system. It performs several important tasks to ensure the efficient functioning of the system and to provide a smooth user experience. Let's discuss each of the mentioned responsibilities of the process manager in detail:

a) Status of each program:
One of the key responsibilities of the process manager is to keep track of the status of each program running in the system. This includes monitoring the execution of programs, checking for any errors or exceptions, and ensuring that the programs are running as intended. The process manager maintains a record of the current state of each program, such as whether it is actively running, waiting for input/output, or terminated. By keeping track of the status of each program, the process manager can efficiently manage system resources and schedule the execution of different programs.

b) Information to a programmer using the system:
Another important responsibility of the process manager is to provide information to the programmers using the system. This includes providing feedback on the execution of their programs, notifying them of any errors or exceptions encountered, and assisting them in debugging and troubleshooting their code. The process manager may generate logs or error messages that programmers can refer to in order to identify and resolve issues in their programs. By providing relevant information to the programmers, the process manager helps them understand the behavior of their programs and enables them to make necessary improvements.

c) Both of the mentioned:
Since both the responsibilities mentioned above are integral parts of the process manager's role, the correct answer is option 'C': Both of the mentioned. The process manager not only keeps track of the status of each program but also provides information and assistance to the programmers using the system. By effectively performing these tasks, the process manager ensures the smooth execution of programs and facilitates the development and debugging processes.
