Understanding the Answer

Let's break down why this is correct

Answer

Negative feedback in an op‑amp reduces its gain but keeps its output from oscillating, giving the circuit a predictable, stable behavior. Similarly, a car’s speed control (like a cruise‑control system) limits how fast the vehicle accelerates and decelerates, preventing sudden jerks and keeping the ride smooth. Both mechanisms sacrifice some maximum performance (maximum gain or maximum speed) to gain steadiness and predictability. For example, if you hit the gas hard, a car with no speed control will surge and then slam on brakes, whereas a speed‑controlled car will ease into the desired speed and stay there.

Detailed Explanation

Road signs that set speed limits tell drivers how fast to go. Other options are incorrect because An open throttle lets the engine run freely, which can make the car accelerate too fast; Accelerating means the car keeps speeding up without limits.
