All neurons have one axon.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -No neuron ever has more than one axon; however in invertebrates such as insects or leeches the axon sometimes consists of several regions that function more or less independently of each other. Axons are covered by a membrane known as an axolemma; the cytoplasm of an axon is called axoplasm.

Detailed explanation-2: -A neuron typically has one axon that connects it with other neurons or with muscle or gland cells. Some axons may be quite long, reaching, for example, from the spinal cord down to a toe.

Detailed explanation-3: -Some neurons have multiple axons or lack axons all together. Multipolar neurons can be classified on the basis of their dendritic branching pattern and shape of the soma into stellate, pyramidal, fusiform, Purkinje, and glomerular cells.
