The primary source of irrigation in Telangana is:

The correct answer is: C) Wells and borewells.

Wells and borewells are the primary source of irrigation in Telangana. This is because the state has a semi-arid climate with low rainfall. Wells and borewells provide a reliable source of water for irrigation, even during droughts.

Canals are

also used for irrigation in Telangana, but they are not as reliable as wells and borewells. This is because canals are often affected by droughts and floods.

In conclusion, the primary source of irrigation in Telangana is wells and borewells. This is because the state has a semi-arid climate with low rainfall. Wells and borewells provide a reliable source of water for irrigation, even during droughts.
