Solution
The correct option is C Acetyl choline
Neurotransmitters are the chemicals that transmit the nerve impulse across the synapse. The first impulse is received by the sensory neuron. This neuron has telodendrons which are knob-like structures at the axonic end. These telodendrons release the neurotransmitter acetylcholine. Acetylcholine is received by the receptors located on the dendrites of another neuron that results in the transmission of impulses. Thus, the correct answer is option C.
