If a purely competitive firm is facing a situation where the price of its product is lower than the average cost, then all of the following applies, except:
a) Other firms will want to enter the industry because of the positive economic profits
b) The firm may earn economic profits in the long run if it expands its plant to exploit economies of scale
c) The firm may be earning some accounting profits, but less than what it could earn elsewhere
d) The firm is suffering losses, and if things are not expected to improve, the firm will leave the industry
