Answer: A. Fuel costs in China have risen sharply and are not expected to drop.
Explanation:
The main reason that companies would want to invest in another country and set up factories there for production, is usually because of the cost savings that it would enjoy doing so.
China offers a lot of cost savings to manufacturers such as with labor and material but if it is found that fuel costs have risen sharply and will not drop anytime soon, production in China will become more expensive and might dissuade companies like Emerson from setting up shop there.
