Tank irrigation is commonly found in South-Central parts of India. What could be the reason?
- 1Insufficient shallow ground water.

Select the correct answer using the code given below:
General KnowledgeGeography
- A1 only
- B1 and 2 only
- C2 and 3 only
- D1, 2 and 3
Explanation
Tank irrigation dominates the rocky Deccan plateau of south-central India because shallow groundwater there is insufficient (1), and the impervious rocky surface with natural depressions favours storage of water in tanks (2). Per the official answer key, 1 and 2 only — option B. (The undulating-terrain argument in statement 3 is plausible but is excluded by the key.)
