Answer:
Alice should exercise the option and pay $100,000 for the land.
Step-by-step explanation:
As Alice has paid $20,000 for the option to acquire the land of ten acres.
In 1985, the worth of land was $120,000 but in 1992, the worth changed to $110,000. She should exercise the option because the inflation rate is the reason in the decrease in the worth of land. By buying the land, she can utilize the land by investing in it instead of holding the money as it will depreciate. By investing the money, she will get the profit and will increase in her wealth. Moreover, she can use other options by selling to another person after adding some value to the land and can get the profit.
