Answer (B) is correct . A firm should continue increasing production as long as marginal cost is less than selling price. Profit is maximized when marginal cost equals selling price (in pure competition, selling price is the same as marginal revenue).Now, MR =10, MC = 7, So the company need to increase production to increase the cost.
Answer (A) is incorrect because A firm in pure competition should increase production as long as the marginal cost is less than selling price.
Answer (C) is incorrect because A firm should not shut down as long as selling price exceeds variable cost.
Answer (D) is incorrect because A firm in pure competition should continue increasing production as long as the marginal cost is less than selling price.
