Up/Down Arrow Keys are used for?

  2. Scroll back and forward through your terminal.

  3. Scroll through your most recent commands.

  4. List the interrupts in use.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

C is correct because in bash and most Unix shells, up/down arrow keys navigate through command history, scrolling through previously executed commands. A is incorrect - memory info requires commands like 'free' or 'top'. B describes Shift-PageUp/PageDown behavior, not arrow keys. D would require commands like 'cat /proc/interrupts'.
