A neuron with one axon and two or more dendrites is known as:

Multipolar.

The correct answer is Option (2) -Multipolar.

A neuron is a microscopic structure composed of three major parts, namely, cell body, dendrites and axon.The axons transmit nerve impulses away from the cell body to a synapse or to a neuro-muscular junction. Based on the number of axon and dendrites, the neurons are divided into three types, i.e., multipolar (with one axon and two or more dendrites; found in the cerebral cortex), bipolar (with one axon and one dendrite, found in the retina of eye) and unipolar (cell body with one axon only; found usually in the embryonic stage).
