When humans experience excessive heat loss, the nervous system sends random signals for skeletal muscles to contract, resulting in shivering. This then raises the body temperature due to the production of heat. This physiological mechanism is most similar to which other process?

(A) When a B-cell receptor binds to an infectious agent, signaling occurs to stimulate a larger immune response.
(B) When blood sugar levels are sensed to be high in the body, insulin is released and blood sugar in the bloodstream drops.
(C) When the uterus is stretched during contractions, this signals to the brain that oxytocin should be released that causes stronger contractions.
(D) As fruit begins to ripen it releases ethylene that causes other fruit to ripen as well.
