Answer:
Option-A
Explanation:
The impulse generated in the neuron is transmitted in the form of an electrical signal or action potential which gets converted into a chemical synapse to transmit the signal from one synapse to another synapse.
The junction at which the electrical signal is converted into the chemical signal is called a synapse. The neurons which produce the chemicals called neurotransmitter from the axon terminal is called the presynaptic neuron and the neuron which receives the signal through receptors of the dendrites is known as the postsynaptic neuron.
Thus, Option-A is the correct answer.
