What most accurately describes imperial holdings in 1900

Great Britain held more land than any other colonial state. The colonies of France and Germany were in Africa.

Explanation:

New Imperialism characterizes an era of European powers' colonial expansion. The era included an unparalleled pursuit of territorial acquisitions in other countries. At that time, states focused on growing their empires with new advances and developments in technology, extending their territory via subjugation, and exploiting enslaved countries' resources.

Great Britain had domains in Northeastern America, Australia, South Asia, and South Africa, while France was mainly dominating Africa. Some others such as Portugal, Spain, Germany, and The U.S. have little domains across the world.
