Option (a)

Explanation of Solution

International trade refers to the buying and selling of goods and services across international boundaries. Some countries follow the ideology of free trade while others follow protectionism. Free trade allows the movement of goods and services, capital, labor, etc. to move freely between countries without any trade barriers while protectionism opposes this idea and restricts imports by imposing several tariff and non-tariff barriers.
