Neuromotor transmitter between two nerves at a synapse is
A. Acetylcholine
Reason: The cytoplasm of the synaptic knob contains mitochondria, smooth endoplasmic reticulum, microfilaments, and numerous synaptic vesicles. Each vesicle contains neurotransmitters responsible for the transmission of the nerve impulse across the synapse. The two main neurotransmitters in the vertebrate nervous system: Acetylcholine (ACh) and Noradrenaline although other neurotransmitters also exist.
