Answer:
A. a movement downward along the supply curve.
Explanation:
According to the law of supply, the higher the price, the higher the quantity supplied and the lower the price, the lower the quantity supplied.
This accounts for why the supply curve is positively sloped.
A change in price of a good leads to a movement along the supply curve and not a shift of the supply curve.
