The marginal cost curve is A. Uminusshaped to reflect the bowed out PPF. B. downward sloping to reflect the bowed out PPF. C. upward sloping to reflect increasing opportunity cost. D. upward sloping because marginal cost falls as more of a good or service is produced. E. downward sloping as marginal benefits increase.

upward sloping to reflect increasing opportunity cost.

Explanation:

Marginal cost curve represents the change on total cost when the output is increased by one unit, it is the cost of producing extra unit of output.

The marginal cost curve is usually upward sloping because of the occurrence of diminishing marginal returns. As production increases it costs more to produce extra units so marginal cost curve increases.

This is illustrated in the attached diagram where marginal cost falls slightly and begins to rise continuously till it goes higher than revenue.
