Excise tax
Prices of inputs
Increase in productivity
Price of product
✅ The correct answer is D.
Price of product is not a cause of shift in cost curves of a firm. Cost curves shift in response to changes in two factors: If a technological change results in the firm using more capital, the average fixed cost curve shifts upward and at low levels of output, the average total cost curve may shift upward. At large output levels, average total cost decreases.
