Hope This Helps You!

Answer:
B. Curare will only affect muscles with ACh receptors, paralyzing them.
Explanation:
Acetylcholine receptors are located on the surface of muscle cells, especially in the synapse between muscle cells and nerve cells. Muscles are constantly pumping sodium out of their cells, so, when they are relaxed, there is more sodium outside than inside. When they get the signal from the nerve, the channels open and sodium ions get back inside, starting the process muscle contraction. IF curare binds to the site where Acetylcholine is supposed to act, and thus blocking all this muscle contraction signal, it will produce a progressive paralysis of all muscles.
