Answer:
The correct answer is the letter d. Neither the first nor the second.
Explanation:
GDP (gross domestic product) growth is influenced by various factors, consumption, investment, technology, external sector, etc. The policy of restricting foreign trade by placing barriers to trade has reduced GDP as it burdens one of the drivers of economic growth, for example by reducing exports to the rest of the world and thus GDP. Similarly, restricting foreign portfolio investment contributes to non-GDP growth, as foreign investments play an important role in increasing companies' capitalization, helping them to make more investments. Therefore, both economic policies are wrong.
