Answer:
Botulinum toxin
Step-by-step explanation:
Botulinum toxin is known to hinder the release of acetylcholine into the synaptic cleft at the neuromuscular junction.
This leads to acetylcholine not attaching to its receptors and eventually leading to the inability to have muscle contractions.
Hence, in this case, the correct answer is Botulinum toxin prevents acetylcholine from accumulating in the neuromuscular junction in individuals.
