Explanation:

A foreign subsidiary links buyers and sellers in different countries but it has no manufacturing capability. Its most important function is taking title to products and moving them from the domestic country to a foreign country. A foreign subsidiary is part of a larger corporation that has its headquarters in the country of origin. It takes title of the products, that is to say, it owns the products and controls its sale.

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."
