Axon is that part of a nerve cell which appears as a.
A
Short branch
B
Long branch
C
Granule
D
Central body
Explanation: 

Detailed explanation-1: -axon, also called nerve fibre, portion of a nerve cell (neuron) that carries nerve impulses away from the cell body. A neuron typically has one axon that connects it with other neurons or with muscle or gland cells.

Detailed explanation-2: -Nerve cells are usually very long and branched so that it helps in transmission of signals or electrical impulses over all parts of the body. They divide and re-divide and so cover a large surface area of the body and every portion receives the signals from the central nervous system.

Detailed explanation-3: -Each neuron in your brain has one long cable that snakes away from the main part of the cell. This cable, several times thinner than a human hair, is called an axon, and it is where electrical impulses from the neuron travel away to be received by other neurons.

Detailed explanation-4: -The branches of axons are known as axon collaterales. The axon itself is often surrounded by a membranous material, called the myelin sheath, formed by glia cells.
