1.Which process had the Process ID number 1?

bash
kernel
init
it varies
none

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.

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.
