• A. Isolationism
• B. Imperialism
• C. Nationalism
• D. Colonialism

Answer: (B)

The term that describes the policy of extending a nation's power and influence through colonization or military force is imperialism. This concept primarily refers to the political and economic domination of one country over another, and it often involves the establishment of control through annexation, military conquest, or the establishment of economic dependencies.

Imperialism played a significant role during the 19th and 20th centuries, particularly with European powers expanding their empires across Africa, Asia, and the Americas. This expansion was often justified by a belief in the superiority of the imperial power's culture and the desire to civilize perceived "lesser" societies.

Isolationism, on the other hand, refers to a policy of remaining apart from the affairs or interests of other groups, particularly political ones, which is contrary to the idea of expanding influence. Nationalism emphasizes pride in and devotion to one's nation, focusing on self-governance and independence rather than expansion. Colonialism is closely related but specifically refers to the practice of settling and governing territories, which is one aspect of the broader imperialism policy. Thus, imperialism encompasses both military and economic aspects of a nation's expansion.
