Arteriosclerosis is a disease that obstructs blood flow and, therefore, oxygen supply to target organs. A major component of arteriosclerosis is the excessive reproduction of smooth muscle
cells of the blood vessels. Certain drugs may have the potential to reverse or prevent the
unregulated reproduction of the diseased blood-vessel cells. Which of these processes is the
most likely target of these drugs?

voluntary muscles are controlled by the cerebellum.

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
