Correct Answer: C
Explanation/Reference:
Explanation: As with files, all processes that run on a GNU/Linux system are organized in the form of a tree. The root of this tree is init. Each process has a number (its PID, Process ID), together with the number of its parent process (PPID, Parent Process ID). The PID of init is 1, and so is its PPID:
init is its own father.
