• C. The tank irrigation systems are widely found in the states of Tamil Nadu.
• D. None of above

Answer 1

The correct option is B In tank irrigation, a dam is constructed across the river and water is stored in the reservoir and used for agriculture through canals.

A tank is usually a man-made hollow structure on the Earth’s surface, which is used to store rainwater and can be used later for irrigation. The tank systems are widely found in the states of Tamil Nadu, Andhra Pradesh, Maharashtra, Karnataka, Odisha, Madhya Pradesh, Rajasthan and Uttar Pradesh. Although in recent years, the area under tank irrigation has gradually decreased. This is because the tank systems are non-perennial and only dependent on rainwater.

Option B explains perennial canals. In perennial canals, a dam is constructed across the river and water is stored in the reservoir and used for agriculture through canals.
