What is the main difference between a hard disk and RAM?

Answer and explanation

Correct answer: A hard disk provides long-term storage while RAM is temporary working memory

A hard disk is non-volatile storage: it keeps files and programs even when electrical power is removed. RAM is volatile working memory used by currently running programs, so its contents are normally lost when the computer is switched off. Therefore option A is correct. Options B and D wrongly treat the devices as identical, while option C reverses their permanence characteristics.
