In a Diagram Showing the Average Total Cost and Average

In a diagram showing the average total cost and average variable cost curves, the minimum point of the average total cost is

A) at the same level of output as the minimum point of the average variable cost.
B) at a larger level of output than the minimum point of the average variable cost.
C) at a lower level of output than the minimum point of the average variable cost.
D) at the same level of output as the maximum of the total product curve.
