What happens immediately after the BIOS completes its process?

The correct response is that immediately after the BIOS completes its process, POST (Power-On Self-Test) begins. The POST is an essential function of the BIOS that checks the integrity of the hardware components and ensures that everything is functioning correctly before proceeding with the boot process. This includes testing the RAM, CPU, motherboard, and other critical components to guarantee that they are operational.

Once the POST has successfully completed and validated that the necessary hardware is in working order, the system can then move on to load the operating system. This sequence ensures that the computer is prepared to run the system software without hardware issues. Therefore, POST is the initial check that occurs right after the BIOS completes its setup routines.
