The correct answer is option 4, which states that all three options (1, 2, and 3) are correct.

Explanation:

1. Insufficient shallow ground water: One of the reasons tank irrigation is commonly found in South-Central parts of India is because these regions have insufficient shallow groundwater. As a result, the construction of tanks helps in storing rainy season water for irrigation purposes throughout the year.

2. Rocky plateau with impervious surface depression: Another reason is the presence of a rocky plateau with depressions or natural depressions with impervious surfaces. These depressions act as storage reservoirs for rainwater, enabling farmers to use it for irrigation.

3. Undulating terrain helps in accumulation of rainwater in depression or man-made tank: The undulating terrain in South-Central parts of India aids in the accumulation of rainwater in depressions or man-made tanks. This topography facilitates the collection and storage of water, which can then be used for irrigation.

Therefore, all three reasons contribute to the prevalence of tank irrigation in the South-Central parts of India.
