In most areas, developers are required to submit environmental impact studies before work can begin on new construction projects. Suppose that a commercial developer wants to build a new shopping center on an environmentally protected piece of property that is home to a rare threeeyed toad. The shopping complex, if approved by the local planning commission, will cover $10$ acres.

The planning commission wants construction to go forward, since that means additional jobs for the local community, but it also wants to be environmentally responsible. One member of the commission suggests that the developer relocate the toads. She describes the relocation process as follows: "The developer builds the shopping mall and agrees to create $10$ acres of artificial toad habitat elsewhere."

The builder will agree with the proposed solution under what circumstances?

a$.$ There is not enough information given to answer the question.

b$.$ The benefits of building the shopping center outweigh the costs, including that of relocating the toads.

c$.$ There are no circumstances in which the builder will agree to the solution.

d$.$ The additional cost of relocating the toads makes the project unprofitable.
