Answer:
The correct answer is A acetylcholine binds to a receptor protein on the motor end plate
Explanation:
The neurotransmitter acetylcholine is released by the motor neuron during the transmission of signals across a neuromuscular junction.
The released acetylcholine then diffuses the synaptic cleft and binds to the receptor protein present on the membrane of muscle fibre.
This ultimately result in the influx of sodium ion inside the muscle cell thereby causing depolarization to generate an action potential.
