Which of the following is an example of an actuator?

Actuators are devices that take a control signal and produce a physical change, such as motion or force, in the system. A DC motor fits this role because when energized, it converts electrical energy into rotational motion that can drive gears, wheels, fans, or other mechanical components. The other options do not act to move or actuate: the temperature sensor and pressure sensor only measure conditions and output signals representing those measurements, while a microcontroller is a control unit that processes information and issues commands but does not by itself generate mechanical action.
