Rowell Company spent $3 million two years ago to build a plant for a new product. It then decided not to go forward with the project, so the building is available for sale or for a new product. Rowell owns the building now. Which of the following statements is correct?

(A) If the building could be sold, then the after-tax proceeds that would be generated by any such sale should be charged as a cost to any new project that would use it.

(B) This is an example of an externality, because the very existence of the building affects the cash flows for any new project that Rowell might consider.
