Which process had the Process ID number 1?

A. bash

B. kernel

C. init

D. it varies

E. none

Answer: C

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.

Reference: http://www.mandrakeuser.org/docs/mdoc/ref/process.html

Incorrect Answers

A:Process ID number 1 represents init, not bash. B:Process ID number 1 represents init, not the kernel. D:Init always has a process ID of 1. It does not vary. E:Init has a process ID of 1.
