a. the portion of its marginal cost curve that lies above the AVC

Explanation:

In short run, a perfectly competitive produces as long as its price is above its AVC, so revenues can cover total variable cost. If price is below AVC, the firm has to shut down. Since such a firm maximizes profit by equating Price with MC, this condition means that firm's supply curve is its MC curve lying above the (minimum point of) AVC curve.
