I feel like E might be correct too, since verifying the BIOS code integrity seems important, but I’m not 100% certain.

I practiced a similar question, and I believe A is not part of POST duties since the user interface comes later in the boot process.

I’m not entirely sure, but I think B is also correct because it has to identify boot devices, right?

I remember that the BIOS checks the system memory during POST, so I think D is definitely one of the duties.
