Introduction:
Madho village is facing a scarcity of water and the question asks to identify a source of water that is not available in the village during this time. Let's analyze the options to determine the correct answer.

Analysis:
The question provides three options as potential sources of water in Madho village during the water scarcity. We will examine each option to determine if it is a valid source of water during this time.

Tanks:
Tanks are artificial reservoirs that store water. They are commonly used to collect rainwater or water from other sources for future use. In Madho village, tanks are likely to be a source of water during water scarcity. Villagers can rely on the water stored in tanks until the situation improves. Therefore, tanks can be considered as a potential source of water during this time.

Handpumps:
Handpumps are devices that allow people to manually extract groundwater. They are commonly used in areas where piped water supply is not available. In Madho village, handpumps are also likely to be a source of water during water scarcity. Villagers can use handpumps to access groundwater and meet their water needs. Therefore, handpumps can be considered as a potential source of water during this time.

Water trains:
Water trains are special trains that transport water to areas facing severe water scarcity. They are usually deployed in situations where the local water sources are insufficient to meet the demand. While water trains can be a solution during extreme water scarcity, they are not a regular or permanent source of water in Madho village. Therefore, water trains are not a source of water in Madho village during the scarcity.

Conclusion:
Based on the analysis, the correct answer is option D, which states "None of these." Water trains are not a source of water in Madho village during water scarcity. Tanks and handpumps are the likely sources of water in the village during this time.
