Answer:
The correct answer is option D.
Step-by-step explanation:
Even though the democratic republic of Congo is rich in natural resources while Switzerland has almost no natural resources, but Switzerland is among one of the richest countries while Congo is among the poorest.
This indicates that abundant natural resources are not the only factor required for economic growth. Other factors such as human capital, physical capital, state of technology, etc. are also necessary for economic growth. Abundant natural resources cannot be efficiently utilized without these factors.
Even if a country is not rich in natural resources but possesses these factors, it can still have high economic growth.
