A
afferent
B
efferent
C
internal
D
external
Explanation: 

Detailed explanation-1: -Afferent neurons, also called sensory neurons, are the nerve fibers responsible for bringing sensory information from the outside world into the brain. Sensory information may involve special senses, such as vision, hearing, smell, or taste, as well as the sense of touch, pain, and temperature.

Detailed explanation-2: -The peripheral nervous system is further subdivided into an afferent (sensory) division and an efferent (motor) division. The afferent or sensory division transmits impulses from peripheral organs to the CNS.

Detailed explanation-3: -Sensory afferent neurons carry inputs from sensors in the periphery to the central nervous system. The term “afferent” means “carrying into, ” and usually describes the transmission of information towards the brain and spinal cord.

Detailed explanation-4: -Specialized afferent neurons capable of transducing sensory stimuli into NERVE IMPULSES to be transmitted to the CENTRAL NERVOUS SYSTEM. Sometimes sensory receptors for external stimuli are called exteroceptors; for internal stimuli are called interoceptors and proprioceptors.
