Answer: B) Imperialism
Explanation: With the Industrial Revolution, production processes became faster and more efficient than before, and the operations themselves during the production process became routine. The labor force was growing, and due to the invention of steam locomotives, the transport of goods was faster and more efficient, easily transporting goods to the ports, and from there onwards. All this has led to better supply and higher demand for goods, which also means higher demand for raw materials. That is why new resources of raw materials were needed, and therefore a greater need for exploration and the acquisition of new resources. All this leads to conquest and imperialism, where besides the source of raw materials, it was easy to find the cheap labor force for exploiting those resources.
