Final answer:
A government can limit imports by imposing tariffs, which are taxes on imported goods, or through quotas, which restrict the amount of goods that can be imported, as part of protectionist policies.
Therefore, option B is correct.
Step-by-step explanation:
One way a government can limit the amount of imports coming into a country is by imposing tariffs, which are taxes on imported goods. Another method is using quotas, which are numerical limitations on the quantity of products that may be imported. These methods are part of a broader strategy called protectionism, which is designed to protect domestic industries from foreign competition by making imported goods more expensive and less competitive compared to locally produced goods.
While export subsidies and free trade agreements are also related to trade, they function differently. Export subsidies aim to encourage domestic production and exportation of goods by providing financial support, making those goods cheaper on the international market. Conversely, free trade agreements seek to reduce trade barriers between member countries, thus promoting increased trade flows.
