A and C.

Explanation:

There are five foundations of economics:

-Incentives matter.

-Opportunity costs.

-Trade creats value.

-Life is about trade off.

Is a situation in which more of one thing  necessarily means less of something else.

When desicions are made, people are always confronted with multiple alternative actions. Example, waking up for school.

The word marginal in economics means additional.  It requires the evaluation of whether one more unit of something has higher additional benefits than additional costs.
