I think the correct answer is D. contraction, by preventing an action potential from traveling across the sarcolemma. Acetycholine lreceptors are found on the surface of muscle cells, concentrated in the synapse between nerve cells and muscle cells. When the nerve impulses reaches the axon terminals, a chemical called the neurotransmitter is released, in this case the acetylcholine that stimulates skeletal muscle cell. Therefore a disease that inactivates the acetylcholine will prevent the activation of the muscle.
due to the pollution and the evolution by men, the cells in our bodies must lose something in order to get something better, in this case, our ability to avoid cancers, diseases. and sicknesses is lost, but we have evolved into even more intelligent species, thus called HOMO SAPIANS
