Final answer:
A state is not considered an international organization as it is a separate governing entity. Multinational corporations, national liberation organizations, and NGOs all have international characteristics and operate across national borders.
Step-by-step explanation:
The option from the list which is not considered an international organization is a state. A state is a politically organized body of people under a single government. On the other hand, multinational corporations are companies based in one state with operations in others, national liberation organizations may work across national lines to achieve their goals, and nongovernmental organizations (NGOs) are private entities that work on common interests and can operate internationally.
