In a perfectly competitive market, a firm produces and sells a certain amount of goods. Among the following what reflect the firm's profit?

Option 1 -> This calculates Fixed Cost (FC = TC - VC), not profit.

Option 2 -> This is the fundamental formula for profit: Profit = Total Revenue - Total Cost.

Option 3 -> This is meaningless as it subtracts marginal cost from total variable cost, which doesn't represent any economic measure.

Option 4 -> In perfect competition, Average Revenue equals price, so this calculation doesn't yield profit.

Hence, Option 2: Total Revenue - Total Cost -> Profit is defined as the difference between what a firm earns (Total Revenue) and what it spends (Total Cost). This is the standard profit formula used in all market structures, including perfectly competitive markets. If TR > TC, the firm makes economic profit; if TR = TC, the firm breaks even; if TR < TC, the firm incurs a loss. -> correct
