The correct answer is B) The company was given tax incentives to keep their operations local that cancel out their expected savings.
The reason why Dave might recommend not moving operations overseas is "The company was given tax incentives to keep their operations local that cancel out their expected savings."
Dave is suggesting that the best option is to stay and not moving out operations to other countries that have cheap labor and this allows the company to low cost. Dave assures that the company was given tax incentives that are better than the savings expected abroad. These incentives allow the company to stay there, keep the jobs in place, support the employees, and the local community.
Tax incentives are a good way to keep companies from moving to other countries.
