The correct answer is A) Cotton.
Cotton is a major crop in Telangana, but the area under cultivation has declined in recent years. This is due to a number of factors, including the falling prices of cotton, the increasing cost of cultivation, and the shift to other crops such as rice and maize.
Cotton is a major cash crop in Telangana, and it is grown in all the districts of the state. The main cotton-growing areas are the districts of Adilabad, Karimnagar, Warangal, Khammam, Nalgonda, and Ranga Reddy.
The area under cotton cultivation in Telangana has declined from 1.7 million hectares in 2005-06 to 1.2 million hectares in 2015-16. This decline is due to a number of factors, including the falling prices of cotton, the increasing cost of cultivation, and the shift to other crops such as rice and maize.
The prices of cotton have been falling in recent years due to the global oversupply of cotton. This has made it difficult for farmers to make a profit from cotton cultivation.
The cost of cultivation of cotton has also been increasing in recent years. This is due to the increasing cost of inputs such as fertilizers, pesticides, and labor.
In addition, farmers are shifting to other crops such as rice and maize, which are more profitable. This is due to the fact that the prices of rice and maize have been rising in recent years.
The decline in the area under cotton cultivation is a major concern for the state of Telangana. This is because cotton is a major source of income for the farmers of the state. The decline in the area under cotton cultivation is also likely to have a negative impact on the economy of the state.
