Choose one: A. The demand for drug X shifts to the left, and the supply curve for drug X shifts to the left. The result is a rise in the equilibrium price for drug X and a fall in the equilibrium quantity of drug X. B. The demand for drug X shifts to the right, and the supply curve for drug X shifts to the left. The result is an unknown change in the equilibrium price for drug X and a fall in the equilibrium quantity of drug X. C. The demand for drug X shifts to the left, and the supply curve for drug X shifts to the left. The result is an unknown change in the equilibrium price for drug X and a fall in the equilibrium quantity of drug X. D. The demand for drug X shifts to the right, and the supply of drug X shifts to the left. The result is a rise in the equilibrium price for drug X and a fall in the equilibrium quantity of drug X.
