Answer:
A) a movement down and to the left along the supply curve for oranges
Step-by-step explanation:
Supply curve shows a relationship between the price of goods and the quantity supplied. It tells the amount that producers are willing to supply at each price. The curve shows a plot of price against quantity supplied by the suppliers.
When the price of the orange decreases, producers would not be willing to supply more oranges, therefore the quantity of orange supplied would decrease. Thereby causing a movement down and to the left of the supply curve as a result of decrease in quantity supplied.
