at the neuromuscular junction, ___ is released into the synaptic cleft, stimulating the skeletal muscles.
nicotine
ach
potassium
sodium

Explanation:

At the neuromuscular junction, the neurotransmitter released into the synaptic cleft to stimulate skeletal muscles is Acetylcholine (Ach). Nicotine is a drug that can interact with receptors but isn't the primary neurotransmitter here. Potassium and sodium are ions involved in action potentials but not the neurotransmitter released at the neuromuscular junction for muscle stimulation. So the correct option should be Ach.

Answer:

B. Ach
