Answer:
The correct answer is letter "C": the supply curve for apples has shifted to the left.
Step-by-step explanation:
The supply curve plots in a graph the relationship between the price and quantity supplied of a good or service. According to the supply law, that relationship is directly proportional meaning if the price rises the quantity demanded increases -the supply curve moves to the right- but if the prices fall the quantity demanded drops -the supply curve moves to the left.
