The correct answer is C) protectionism.
National defense, helping infant industries, reducing domestic job loss, and keeping money at home are MOST LIKELY arguments in protectionism.
When a nation applies a protectionist economic system it means that it approves practices like the mentioned above and practically isolated its economy from the global economic scenario. The consequences these nations suffered from that decision is that other nations stop trading with them or drastically reduce their imports. People from those protectionist countries suffer from a lack of jobs due to trade restrictions.
That is why, in a globalized world, trade has helped countries to prosper and form free trade associations such as NAFTA, the North America Free Trade Agreement between México, the United States, and Canada.
