A reflex is an involuntary movement that is elicited by an external stimulus. This means that it is not under conscious control and is a response to something happening outside of the body. Choice B is incorrect because voluntary movements are under conscious control, while reflexes are not. Choices C and D both have parts of the correct answer, but only A has both parts correct (involuntary and external). Choice E is incorrect because reflexes are not related to mental or psychological stimuli.
