The correct answer is option 1. The nature of the colonial city changed in the mid-nineteenth century. After the Revolt of 1857 British attitudes in India were shaped by a constant fear of rebellion. They felt that towns needed to be better defended, and white people had to live in more secure and segregated enclaves, away from the threat of the ‚¬Å“natives‚¬. Pasturelands and agricultural fields around the older towns were cleared, and new urban spaces called ‚¬Å“Civil Lines‚¬ were set up. White people began to live in the Civil Lines. Hence, statement 1st incorrect as Civil Lines were not set up, to accommodate Indian elites. For the British, the ‚¬Å“Black‚¬ areas came to symbolise not only chaos and anarchy, but also filth and disease. Hence, statement 2nd is correct. For a long while the British were interested primarily in the cleanliness and hygiene of the ‚¬Å“White‚¬ areas. But as epidemics of cholera and plague spread, killing thousands, colonial officials felt the need for more stringent measuresof sanitation and public health. They feared that disease would spread from the ‚¬Å“Black‚¬ to the ‚¬Å“White‚¬ areas. From the 1860s and 1870s, stringent administrative measures regarding sanitation were implemented and building activity in the Indian towns was regulated. Underground piped water supply and sewerage and drainage systems were also put in place around this time. Sanitary vigilance thus became another way of regulating Indian towns. Hence, statement 4th is correct. Cantonments, hill stations were distinctive features of colonial urban development. The founding and settling of hill stations was initially connected with the needs of the British army. Hill stations became strategic places for billeting troops, guarding frontiers and launching campaigns against enemy rulers. Hence, statement 3rd is correct.
