Rigour is best described as?

Rigour describes the body's response when fever rises: violent shivering as the muscles contract rapidly to generate heat in order to reach a higher temperature set-point. This happens because infection or inflammation triggers pyrogens that signal the hypothalamus to raise the body's temperature. The shivering is the hallmark feature, making it the best match for rigour. The other options describe different symptoms (a mild tremor after exercise, a rash with allergy, or nausea with fever) and do not capture the characteristic intense shaking that accompanies a fever.
