The following relationship must hold between the average total cost (ATC) curve and the marginal cost curve (MC) :

A) If MC is rising, ATC must be rising.
B) If MC is rising, ATC must be greater than MC.
C) If MC is rising, ATC must be less than MC.
D) If ATC is rising, MC must be greater than ATC.
E) If ATC is rising, MC must be less than ATC.

Average Total Cost

The total cost of production (fixed and variable costs combined) divided by the total output, indicating the average cost per unit of output.

Marginal Cost Curve

A graphical representation showing how the cost to produce one additional unit changes with the level of production.

Rising

Often refers to the increase in value, quantity, or level of something over time, frequently used in the context of prices, temperatures, or other measurable factors.
