The correct answer is B. Decreasing.
Agriculture is the primary source of livelihood for more than half of India’s population. However, its contribution to the country’s GDP has been declining in recent years. In 2019, agriculture contributed only 15.8% to India’s GDP, down from 26.6% in 1991.
There are several reasons for this decline. First, India’s economy has been growing rapidly in recent years, and the service sector has been the main driver of this growth. Second, agriculture has been facing a number of challenges, including low productivity, water scarcity, and climate change. Third, the government has been investing more in other sectors, such as manufacturing and infrastructure.
Despite the decline in its contribution to the GDP, agriculture remains an important sector of the Indian economy. It provides employment to millions of people and is a major source of food for the country. The government has taken a number of steps to revive the agricultural sector, including providing subsidies, investing in irrigation and research, and promoting agricultural exports.
Option A is incorrect because the contribution of agriculture to the Indian economy is declining. Option C is incorrect because the contribution of agriculture to the Indian economy is not constant. Option D is incorrect because the contribution of agriculture to the Indian economy is not none of the above.
