Answer:
c) is reflected in a downward sloping supply curve.
Explanation:
A direct relationship between the price and quantity is reflected in a downward sloping supply curve.
The Law of demand states that ''conditional on all else being equal, as the price of a good increases, quantity demanded decreases; conversely, as the price of a good decreases, quantity demanded increases"
Hence this relationship is reflected in a downward sloping curve as demand falls as price rises.
