The correct option is B Imperialism
Imperialism occurs when a strong nation takes over a weaker nation or region and dominates its economic, political, and cultural life. These new areas or weaker regions were called Colonies. After the Industrial Revolution, it became a common practice of European nations seeking new sources of raw materials and markets to sell manufactured products. The western countries sought to expand their economies by obtaining raw materials from the colonies which could be transported back to factories and are turned into manufactured goods. Ultimately, the finished goods are shipped back to the colonies markets for sale thus making a profit.
