Solution
The correct option is C I and III Nissl’s granules are fragments of rough endoplasmic reticulum (RER). They are involved in protein synthesis and are found only in specific parts of the neuron; in the cyton as well as the dendrites. They are absent in axon. The glial cells surround neurons and provide support for and insulation between them.
