Solution

The correct answer is (A).

Given is the labelled diagram of a neuron:

$∙$ Neuron is the structural and functional unit of the nervous system. It conducts information in the form of electrical impulses.
$∙$ The dendrites receive the impulse which flows through the axon.
$∙$ On reaching the axon terminal, chemical messengers called neurotransmitters are released.
$∙$ These chemicals cross the synapse and initiate a similar electrical impulse in the dendrite of next neuron.
This is how nervous impulses travel in the body.
