Which of the following is correct as it relates to cost curves?

A) Average variable cost intersects marginal cost at the latter's minimum point.
B) Marginal cost intersects average total cost at the latter's minimum point.
C) Average fixed cost intersects marginal cost at the latter's minimum point.
D) Marginal cost intersects average fixed cost at the latter's minimum point.

Marginal cost intersects average total cost at the latter's minimum point is correct. This is because the minimum point of average total cost represents the most efficient level of production, where the firm is producing output at the lowest possible cost per unit. At this point, the marginal cost, which represents the extra cost of producing one additional unit of output, is equal to the average total cost, which represents the total cost of producing all units of output divided by the total number of units.
