Answer

B) economies and diseconomies of scale. Explanation 1. Identify the concept The U-shape of the long-run average total cost (LRATC) curve is due to changes in cost per unit as output changes. 2. Understand economies and diseconomies of scale **Economies of scale** occur when increasing production leads to lower average costs, causing the downward slope. **Diseconomies of scale** occur when further increases in production lead to higher average costs, causing the upward slope. 3. Relate to LRATC curve The combination of economies and diseconomies of scale results in the U-shape of the LRATC curve.
