The correct answer is D. They allowed industrial goods to be easily shipped to foreign markets.
Step-by-step explanation
The Panama Canal is an 82km long navigation route that connects the Caribbean Sea with the Pacific Ocean, crossing the entire country of Panama; The Suez Canal is a 163 km long waterway that connects the Mediterranean Sea with the Red Sea. These two waterways are artificial and were built to contribute to international trade because they shortened the distances that had to be traveled. For example, before the construction of the Panama Canal, South America had to be surrounded (it shortened the road between America, Europe, Africa, Asia and Oceania) and in the case of the Suez Canal, the continent of Africa had to be surrounded (it shortened the road between Europe, Africa, Asia and Oceania). The construction of these two roads allowed the growth of international industrialization because they allowed industrial products to be easily shipped to the foreign market. So the correct answer is D.
