Final answer:
Outsourcing, offshoring, and foreign direct investment are all ways in which activities can be located in another nation.
Step-by-step explanation:
Outsourcing is the practice of hiring labor from sources outside of the company or outside of the nation in which the company is located. Offshoring, on the other hand, refers to the process of moving some of a company's operations overseas to access cheaper labor markets. Foreign direct investment involves a company conducting its own operations but physically moving them overseas. Therefore, the correct answer to the question is option D, all of the above, as all three options - outsourcing, offshoring, and foreign direct investment - involve locating activities in another nation.
