Answer:
None of the multiple choices is correct. The correct answer should be: "Business profit will increase by $12,000 per year"
Step-by-step explanation:
$12,000 per year is the rental rate.
If his Uncle Fred gives him the building, George will not pay the rental fee. Thus, the business profit will increase by $12,000 per year.
If we consider about the economic profit or implicit cost, it will not change.
