imagine that in 2016 a US firm acquired a plant in France. In 2017 that plant accounted for 10% of the US firm's sales. Why is the US firm not a multinational enterprise?

a. the US firm IS a multinational enterprise because it is engaged in foreign direct investment

b. its foreign sales took place in a different year than its foreign acquisition

c. because of its trade agreements with France, a U.S firm operating there is not considered multinational.

d. its foreign sales are less than 25%

No explanation needed, only the answer. It is urgent.
