An economist has estimated that the maintenance of a public park costs $25,000 a year and that the public park generates $30,000 a year in revenue for merchants near the park. From society's point of view, the maintenance of this park is

B) inefficient because the additional revenues generated by the park are so low.
C) potentially efficient because the value of the gains exceed the value of the costs.
D) potentially efficient because no one would be made worse off as a result of maintaining the park.
