Solution

The correct option is B All are chemicals transmitters
The neurotransmitters are the chemical molecules that are used by the nervous system to transmit the nerve impulse between the neurons and to the muscles. The effects of the neurotransmitters can be excitatory, inhibitory or modulatory. Acetylcholine was the first neurotransmitter to be discovered. It is released by the neurons of the parasympathetic nervous system. Noradrenaline is the primary neurotransmitter of the sympathetic nervous system. Serotonin is also used as a neurotransmitter to induce the sleep, memory, appetite etc.
Hence, the correct answer is 'All are chemical transmitters'.
