Final answer:
A multinational structure allows subsidiaries of a company to operate autonomously while reporting to the parent company. Multinational corporations control production in multiple countries and significantly influence global economics and politics.
Step-by-step explanation:
In a multinational structure, a company's subsidiaries operate autonomously but regularly report to the parent company. Multinational corporations (MNCs) are corporate business entities that control the production of goods and services in multiple countries. Characteristics of multinational corporations include that they collect a large share of their capital from a variety of different nations, conduct business without regard to national borders, concentrate wealth in the hands of core nations and already wealthy individuals, and play a key role in the global economy. Multinationals can both positively and negatively impact the nations where they do business.
It's important to note that not all MNCs are headquartered primarily in the United States, as choice d from the provided options might suggest. This is a common misconception about these entities. Additionally, the anarchic nature of the international system makes the global level of analysis particularly unpredictable, given the numerous non-state actors like multinational corporations and NGOs influencing politics and economics at this level.
