{'solar energy': [6, 1, 0, 3], 'minor irrigation projects': [0, 1, 0, 0], 'residential buildings': [0, 1, 0, 0], 'supply water': [0, 1, 0, 0], 'technology': [1, 5, 15, 27], 'iv': [6, 110, 77, 8], 'india': [8, 1, 7, 13]}

The correct answer is 1, which states that all four mentioned uses of solar energy at the current level of technology available in India are feasible.

I. Supplying hot water to residential buildings: Solar water heaters utilize the sun`s energy to heat water efficiently. These systems are widely available and can be easily installed in homes.

II. Supplying water for minor irrigation projects: Solar-powered pumps can pump water from different sources like bore wells, canal, pond etc., which can be used for minor irrigation purposes.

III. Providing street lighting: Solar street lights are becoming increasingly popular as they are energy-efficient, cost-effective and environmentally friendly. Their installation and operation are feasible with the current solar technology available.

IV. Electrifying a cluster of villages and small towns: With the advent of solar microgrids and solar home systems, it is possible to provide electricity to remote or off-grid areas like villages and small towns.

Hence, all four options are possible and correctly indicate the various uses of solar energy using the current technology available in India.
