Answer

D

Explanation

Based on the number of axon and dendrites, the neurons are divided into three types :
1. Unipolar : Cell body with one axon only, found usually in the embryonic stage.
2. Bipolar: With one axon and one dendrite, found in the retina of eye.
3. Multipolar: With one axon and two or more dendrites, found in the cerebral cortex.
