Correct Answer is :

C. 1

Explanation

The process ID (PID) of the init process is: 1

• The init (or its modern replacement like systemd) is the first process started by the kernel during system boot.
• It is the parent of all other processes on a Unix/Linux system.
• Since it is the first process, it is always assigned PID 1.
