Answer:
The correct answer is option C.
Step-by-step explanation:
Platinum is a relatively rare metal vital to a wide variety of industries.
Xagor Corporation, a major producer of platinum, has its production plant in a country. The country is going to impose an export tax on platinum sold and shipped to customers abroad. This will cause the world price of platinum to increase.
This is possible because of the scarcity of platinum. The production and supply of platinum from other countries are not able to meet the global demand for platinum. An export tax will increase the price of platinum in the country. Since the other countries are taken together cannot meet the worldwide demand. The world price will rise as well.
