Question

one method for studying opportunity cost is to think in terms of
○ risk and ability.
○ pros and cons.
○ tradeoffs
○ trial and error.

Explanation:

Opportunity cost refers to the value of the next best alternative that is forgone when making a choice. This core concept is directly tied to the idea of tradeoffs, as choosing one option means trading off the benefits of the alternative option(s). The other options do not align with the definition of opportunity cost: risk and ability relate to decision-making constraints, pros and cons are a broad cost-benefit analysis, and trial and error is a learning method.

Answer:

tradeoffs
