Answer:

The correct answer is option A) An industry's supply curve is built upon firm entry and exit decisions and their effects on costs.
An increasing cost industry will have an upward sloped supply curve and for a constant cost industry we can derive a flat/horizontal supply curve and for a decreasing cost industry, we get a downward sloped supply curve.
