In this video, Prof. Das reviews how to identify the cost curves and would like you answer the following question: The intersection of which two curves gives you the efficient scale, and give us an approximate of the efficient scale quantity Group of answer choices Marginal Cost Curve (Curve D) and Average Total Cost Curve (Curve B), Efficient Scale Quantity ~ 2 Marginal Cost Curve (Curve D) and Average Fixed Cost Curve (Curve A), Efficient Scale Quantity ~ 2 Marginal Cost Curve (Curve D) and Average Total Cost Curve (Curve C), Efficient Scale Quantity ~ 2 Marginal Cost Curve (Curve D) and Average Total Cost Curve (Curve A), Efficient Scale Quantity ~ 4
