Explanation
The correct answer is A, Kavaratti.
In May 2005, the National Institute of Ocean Technology commissioned Indias first Low Temperature Thermal Desalination plant at Kavaratti in Lakshadweep. This plant was designed to produce one lakh litres of fresh water per day. The process works by using the temperature difference between warm surface seawater and cold deep seawater to evaporate water under low pressure and then condense it into fresh water. This technology is particularly suitable for island territories like Lakshadweep where fresh water resources are scarce and the surrounding sea is deep enough to provide the required temperature gradient.
