State one advantage of writing programs in assembly language instead of a high-level language.

• Programs written in assembly language can interact reliably with all hardware when executing
• Programs written in assembly language can interact directly with the user when executing
• Programs written in assembly language can interact directly with the hardware when executing
• Programs written in assembly language can interact reliably with all users when executing
