The correct answer is (a) Lakshadweep.
Lakshadweep is a group of islands in the Arabian Sea, off the coast of Kerala. It is one of the most remote and sparsely populated regions in India. The islands are known for their beautiful beaches, clear waters, and coral reefs.
The water desalination plant in Lakshadweep is the first of its kind in India. It was commissioned in 2013 and has a capacity of 10 million liters of water per day. The plant uses reverse osmosis technology to desalinate seawater.
The water desalination plant in Lakshadweep is a major achievement for the Indian government. It will help to improve the water supply in the islands and reduce the dependence on groundwater. The plant will also help to protect the environment by reducing the use of plastic bottles.
