The correct answer is B. F5.
When you start your computer, DOS loads the CONFIG.SYS and AUTOEXEC.BAT files. These files contain instructions that tell DOS how to set up your computer and what programs to run when you start it up.
If you press the F5 key while your computer is starting up, DOS will bypass the CONFIG.SYS and AUTOEXEC.BAT files and load a command prompt. This means that you will be able to type commands directly into DOS instead of having DOS run programs automatically.
The other options are incorrect.
- Option A, F8, is used to edit the CONFIG.SYS and AUTOEXEC.BAT files.
- Option C, F4, is used to display a list of commands that you can type at the command prompt.
- Option D, F1, is used to display help information.
- Option E, None of the above, is incorrect because F5 is the correct answer.
