Explanation:

Puri became the first city in India where people can avail high quality drinking water directly from the tap on 24-hour basis. Henceforth, people need not have to store or filter drinking water.

• No metropolitan city in India have such facility yet. Similar facilities are available only in world-class cities like London, New York and Singapore.
• The project would benefit 2.5 lakh citizens of Puri and 2 crore tourists who visit the tourist place every year. They need not have to move around with water bottle. Puri would no more be burdened with 400 metric tonne of plastic waste. Water fountains have been developed at 400 locations in Puri.
• A similar project is under various stages of implementation in 16 other urban centres of Odisha.

Hence option 1st is correct.
