Which country had the largest colonial empire at one time?

France

Great Britain

United States

Germany

The correct answer is B) Great Britain

Explanation:

At one time, Great Britain had the largest Empire in world history. It was famously said that the 'Sun never sets on the British Empire'

This was in reference to the size of the Empire which was so large that at any given moment the sun always shined on at least one it's territories.

As an example, modern countries of Canada, Australia, the United States, India and large parts of Africa were all part of the British Empire.
