The correct option is B Dendrite
A neuron has three main parts:dendrites, an axon, and a cell body or soma.
The cell body has a nucleus, Golgi body, endoplasmic reticulum, mitochondria and other components.
Dendrite are branch-like structures that arise from the cell body. They receive messages from other neurons and allow the transmission of messages to the cell body.
Axon carries electrical impulse from the cell body to the axon terminals that passes the impulse to another neuron. Sometimes the axons of the neurons are covered by a myelin sheath which helps in faster conduction.
