Answer: c

Explanation: In the short run ATC = AFC + AVC (average total cost equals average fixed cost plus average variable cost). Other options are incorrect: ATC is not MC + AVC or MC + AFC; ATC is typically U‑shaped so it does not always rise with output; and ATC is not zero if the firm shuts down because fixed costs still exist.
