When your body temperature drops below normal, your muscles contract rapidly, which generates heat. This is an example of an effector, which is the component of a feedback system that carries out a response to the stimulus. The sensor detects the change in temperature, and the control center (such as the hypothalamus in the brain) processes the information and sends signals to the effector to initiate a response. In this case, the effector is the muscles contracting to generate heat. Therefore, the correct answer is B.
