Explanation
An international governmental organization is the name of a group of countries that come together to establish an international organization to establish norms and guidelines for relationships. One of the best-known international governmental organizations is the United Nations, which was created after the Second World War to establish norms and guidelines in relations between countries and to have a neutral entity that mediates conflicts between countries and avoids conflicts like world wars. On the other hand, the countries that are part of the United Nations allow this organization to operate in this country. So the correct answer is B. Are able to operate in every country that is part of the group.
