The correct option is A Dorsal root ganglia
The nervous system is made up of a central nervous system which includes the brain and the spinal cord and a peripheral nervous system consisting of a network of neurons. The neurons that receive information from the sensory organs and transmit this to the central nervous system are called afferent neurons while neurons that send impulses from the central nervous system to the organs are called efferent neurons. The cell bodies of the afferent neurons are located in the dorsal root ganglia. So, the correct answer is option A.
