Solution

The correct option is C Both a and b
CNS includes brain and spinal cord. Afferent fibres are made of dendrites and efferent fibres are made up of axons. Sensory nerves contain only afferent fibers, which are long dendrites of sensory neurons. Motor nerves have only efferent fibers, which are long axons of motor neurons. Mixed nerves contain both types of fibers. Nerves of CNS have both afferent and/or efferent fibres.
