Opportunity cost

A.
only is considered for goods in short supply.
B.
is the value of the next best alternative as a result of choosing some given alternative.
C.
is the value of all alternatives forgone as a result of choosing some given alternative.
D.
either B or C.

D. either B or C.

The correct answer is D. Opportunity cost is defined as the value of the next best alternative that is forgone as a result of choosing a particular option. In other words, it is the value of all alternatives that are given up when making a decision. So, option D, which states that opportunity cost is either the value of the next best alternative (option B) or the value of all alternatives forgone (option C), is correct.
