How do the roles of AVC and ATC differ in the formation of the supply curve in the short run and long run?

In the short run, the supply curve is the portion of the marginal cost curve above AVC, while in the long run, it is above ATC.

In the short run, the supply curve is above ATC, while in the long run, it is above AVC.

In both the short run and long run, the supply curve is the entire marginal cost curve.

In both the short run and long run, the supply curve is the portion of the marginal cost curve below AVC.
