Freley Enterprises is considering two different development plans for an old building

they own and want to restore. The building was purchased five years ago for $$237,500.$

The first plan is to create an executive resort and conference center at an estimated

cost of $$2\mathrm{.}1$ million. The second plan is to develop luxury apartments with a total cost

of $$3\mathrm{.}4$ million. Of course, there is always the third option, and that is to take the offer

they just received of $$275,000$ and sell the property. Which one of the following values

represents the opportunity cost of this project?
