Haha, option D made me laugh. It's like saying the wheel is designed to slow down your car.

Option D is just silly. The interrupt mechanism is designed to enhance real-time and execution efficiency, not reduce it.

I think option A is better because it allows the CPU to be more efficient by handling other tasks when peripherals don't need intervention.

Option A is definitely the correct answer. The interrupt mechanism allows the CPU to focus on other tasks while the peripherals handle their own work.
