Answer : The correct answer is -
d.terminal branches.
Neuron (nerve cell) is the functional unit of nervous system, which helps in the transmission of impulses throughout the body.
It is primarily composed of four parts-
Dendrites ( that receive message from previous neuron), cell body, axon, and axon terminal/terminal branches (present at the end of neuron) that release neurotransmitter in the synapse (gap between two neuron), which is taken by the adjacent neuron as chemical message.
Thus, terminal branches are the structures that transmit information to other neuron in the form of neurotransmitter.
