An example of a multinational corporation (MNC) is:

A multinational corporation (MNC) is defined as a company that operates in multiple countries while managing production or delivering services in more than one nation. GM, or General Motors, exemplifies this definition as it is an automotive company that has manufacturing plants and business operations across various countries, including the United States, Canada, and several nations in Asia and Europe.

The nature of MNCs involves not only the geographical spread of operations but also the ability to impact local economies and engage in international trade. GM's global presence allows it to leverage economies of scale, tap into different markets, and diversify its operations in a way that smaller firms cannot.

The other entities listed do not fit the definition of an MNC. Oxfam is a non-governmental organization focused on alleviating poverty and fighting inequality, the World Trade Organization functions as an intergovernmental organization that regulates international trade, and Black Lives Matter is a social movement advocating for racial justice. None of these organizations have the commercial aims or operational structure that defines multinational corporations.
