D) ​habitual response.

Quizplus · Accepted Answer

A reflex arc is the simplest behavior in which a stimulus provokes an automatic response. It involves a sensory neuron, an interneuron, and a motor neuron. The sensory neuron detects the stimulus, the interneuron processes the information, and the motor neuron sends a signal to produce the response. Examples include the knee-jerk reflex and the withdrawal reflex.

B, C, and D are not correct because there is no such thing as neurilemma, cranial arc, or habitual response in this context. The neurilemma is a part of a neuron, but it does not relate to behavior directly. The cranial arc and habitual response are not recognized terms in psychology or neuroscience.
