The correct answer is (a) Himachal Pradesh.
Himachal Pradesh is the first state in India to use Gross Environment Product (GEP) in its Gross Domestic Product (GDP) calculation. The GEP is a measure of the value of all the goods and services produced by a country, including the value of the country’s natural resources. The GDP is a measure of the value of all the goods and services produced by a country, excluding the value of the country’s natural resources.
The use of GEP in GDP calculation is important because it helps to account for the value of the country’s natural resources. This is important because natural resources are a valuable asset that can be used to generate economic growth. The use of GEP can also help to ensure that the country’s natural resources are used in a sustainable way.
The use of GEP in GDP calculation is not without its challenges. One challenge is that it can be difficult to accurately measure the value of natural resources. Another challenge is that the use of GEP can lead to changes in the way that economic growth is measured. However, the use of GEP is an important step in ensuring that the country’s natural resources are used in a sustainable way.
The other options are incorrect because they are not the first state in India to use Gross Environment Product in its Gross Domestic Product calculation.
