Answer:
D) MNEs may transfer profits back to the home country without restriction.
Explanation:
One of the largest obstacles that multinational enterprises (MNE) face when carrying out foreign direct investments is that they must be sure that they will be able to recover their investment and have access to the profits generated by the foreign subsidiaries. It makes no sense to open a subsidiary in a country that will not let money be sent to the corporation's headquarters. E.g. Iran faces severe economic sanctions that basically isolate it from the rest of the word, so investing in Iran is a really bad idea because no matter how profitable a company might be, the profits will remain there.
