Answer:
The correct answer here is C) .
Explanation:
The perfect competition is a form of market where there are large numbers of buyers and sellers, and all the sellers are selling same type of products without much of differentiation. Here the demand curve of the market will be downward sloping because when the price of a product increase than the demand for that product will decrease. Here the prices are set by the market forces of demand and supply, individual firms are just price takers and that's why their demand curve is horizontal to the equilibrium price of market.
