A
AC = AR
B
TC = TR
C
MC = AC
D
MR = MC
Explanation:

Detailed explanation-2: -In the perfect competition market the must be fulfilled for an industry to be in equilibrium they are: Quantity demand equal to Quantity supply i.e. (QD = QS) Marginal cost (MC) Equal to Marginal Revenue (MR) e. (MC = MR) and Marginal cost (MC) cuts Marginal Revenue (MR) from below.

Detailed explanation-3: -Equilibrium in perfect competition is the point where market demands will be equal to market supply. A firm’s price will be determined at this point. In the short run, equilibrium will be affected by demand. In the long run, both demand and supply of a product will affect the equilibrium in perfect competition.
