Answer:
The answer is A.
Step-by-step explanation:
Supply curve tells us the quantity of products that sellers are willing and able to sell at a certain price at a particular point in time.
This is in contrast with demand curve which shows the quantity of products that buyers are willing and able to buy at a certain price at a particular point in time.
The supply curve slopes upward which means a producer will be willing to increase its production as the price of the product increases.
