One advantage of a closed loop feedback system is:

In a closed-loop feedback system, the output is continually measured and compared to the desired reference so the input can be adjusted to minimize any difference. This setup lets the system detect and counteract disturbances—things that push the output away from the target, such as changes in load, friction, or supply voltage—and drive the output back toward the setpoint. That reactive disturbance rejection is the main advantage, because the system maintains accurate performance even when conditions change. The other statements don’t describe this core benefit. Closed-loop designs are typically more complex due to sensors, computation, and actuators, so simplicity isn’t an advantage. Stability isn’t inherently worse in a closed-loop system; with proper design, it can be stable and even more robust than an open-loop system. While calibration and sensor accuracy matter, the defining plus of closed-loop is its ability to correct for disturbances through feedback.
