Correct Answer: Option D — Delhi
The tower was inaugurated by Chief Minister Arvind Kejriwal at Baba Kharak Singh Marg in Connaught Place. A second, similar tower was also installed shortly after in the Anand Vihar area of the city.

How the Smog Tower Works
The structure is essentially a massive air purifier designed to reduce the concentration of Particulate Matter (PM2.5 and PM10) in the immediate vicinity.

Height: Approximately 24 meters.

Mechanism: It uses a "downdraft" method where fans at the top pull in polluted air, which is then filtered and released through vents at the base.

Capacity: It is designed to clean 1,000 cubic meters of air per second, aiming to impact a radius of about 1 km.

Context of the Project
The installation was part of a pilot project following a Supreme Court order to combat Delhi's notorious winter air pollution. It was a collaborative effort involving Tata Projects Limited, IIT Bombay, and IIT Delhi.
Answer verified by Quintessence Classes faculty — Karan Nagar, Srinagar.
