Final answer:
An example of a country using protectionism in international trade is d. Governmental restrictions and competitive support actions affect trade flows, which include tariffs, import quotas, and nontariff barriers.
Step-by-step explanation:
Protectionism is a government's action to restrict international trade with the aim of shielding domestic industries from foreign competition. The correct answer to the example of a country using protectionism would be d. Governmental restrictions and competitive support actions affect trade flows. This includes measures such as tariffs, import quotas, and nontariff barriers. These tools are used to increase the price of imported goods, making domestic products more competitive. While this supports local producers, it can lead to higher prices for consumers and potential trade disputes with other countries.
Border checks for illegal activities (option a) are more related to immigration control and law enforcement, whereas protectionism focuses on economic policies. Intellectual property protection (option c) does include legislative actions but is not primarily about trade flow. Lastly, payments to prevent theft from shipments (option e) are more of a security measure, not a trade policy.
