C)motor neuron $\rarr$  interneuron in the PNS $\rarr$ sensory neuron
D)sensory neuron $\rarr$  interneuron in the CNS $\rarr$ motor neuron

Quizplus · Accepted Answer

In a reflex arc, the signal typically passes through a sensory neuron first, then an interneuron in the CNS (Central Nervous System), and finally a motor neuron. This sequence allows for a rapid response to stimuli.
