Correct Answer: Option A

Explanation

The two stages involved in booting are the Power On Self Test (POST) and the loading of the operating system. Hence I and II are correct

* Power On Self Test (POST): This is the initial check of hardware components when the computer is powered on to ensure everything is functioning correctly.

* Loading of Operating System: After POST, the computer loads the operating system from storage into memory, allowing the user to interact with the system.
