Which of the following is not a characteristic of multinational corporations?
a large share of their capital is collected from a variety of nationalities.
their business is conducted without regard to national borders.
they concentrate wealth in the hands of core nations.
they are headquartered primarily in the united states.

The correct answer is D. They are headquartered primarily in the United States.

Explanation:

Multinational corporations are a type of corporation that conducts business and produces products or services in two or more countries, which implies these corporations have an influence in different countries usually by establishing a main headquarters in its home country and different branches in other countries and therefore collect shares from different nations. Additionally, multinational corporations are linked to the globalization phenomenon and because of this business of multinational corporations are conducting beyond border although in most cases the multinational corporations are owned by core or wealthy nations such as the U.S. China and Japan.

Considering this, the one that is not a characteristic of multinational corporations is "they are headquartered primarily in the United States", because in most cases multinational corporations are located on core nation that includes the U.S. but also many other nations such as Japan or China and therefore multinational corporations are not exclusively headquartered in the U.S.

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
