Answer:
c. Britain
Explanation:
A sphere of influence or zone of influence is an area or region in which an organization or state exercises some kind of indirect cultural, economic, military or political domination. Also, in some inhabited places, there is talk of an area of influence to designate the space in which, for example, a trade or service has influence over localities or other areas other than those located.
British supremacy over the international scene has resulted in one of the greatest empires in history. Proof of this is, for example, the replacement of French with English as the basic language of international relations. The Anglo-Saxon influx has been spread across different significant geopolitical points: from the American colonies, through the overseas surfaces of the Caribbean, to regions of the Asian and oceanic continents, in addition to an African colonization process over a group of countries on the continent.
