c. colonial expansion

Explanation:

Around 1600, Europeans exploited 49 percent of the globe but only 32 percent of the world's land.

This colonial exploitation made the Europeans known to various peoples with different cultures and appearances, this gave them a racial consciousness that they did not have before colonial expansion.
