Answer: Option (B) is correct.
Step-by-step explanation:
Opportunity cost is the benefit that is foregone for an individual by choosing one alternative over other alternatives available to him.
If the opportunity cost is lower for an individual then this will benefit him whereas if the opportunity cost is higher then this will not benefit the individuals.
The opportunity cost of attending college for Brooke is the amount that she could earn as an actress i.e. $2 million per year.
The opportunity cost of attending college for Sandy is the amount that he could earn by serving hamburgers i.e. $10,000 a year.
Therefore, opportunity cost of attending college is greater for Brooke than for Sandy.
