Final answer:
Countries set trade restrictions to protect domestic industries from competition, restrict foreign influence, and raise the price of imported goods, sometimes as a political tool to punish other nations.
Thus the corret opction is:a.b.c.d
Step-by-step explanation:
Countries establish limits on trade primarily for a few reasons, which are:
- To protect domestic industries and jobs from foreign competition by making foreign products less competitive through tariffs, import quotas, and non-tariff barriers.
- To restrict foreign influence in a sector, particularly in industries deemed essential for national security or cultural identity.
- To raise the price of foreign goods domestically, which in turn may encourage the purchase of domestic products.
- Sometimes trade restrictions are used to punish other countries, but this is generally considered a diplomatic or political tool rather than an economic one.
