Answer 2

Nerve Impluses In a Reflex - Option C

Sensory neurons, interneurons in spinal cord, motor neurons shows the path followed by nerve impulses in a reflex. Sensory neurons are the neurons that carry information from the environment externally to the central nervous system (CNS) mainly brain and motor neurons are those which carry information from CNS to other parts.  

A human perceives something then by sensory neurons the information goes to CNS and that information is further passed by interneurons in spinal cord and is further passed by motor neurons from CNS to other parts to perform stimulus of perception.
