The correct answer is Town Planning. Explanation & Key Takeaways: • Town Planning Under East India Company : • After Wellesley’s departure, the work of town planning was carried on by the Lottery Committee (1817) with the help of the government. • The Lottery Committee was so named because funds for town improvement were raised through public lotteries. • In the early decades of the nineteenth century raising funds for the city was still thought to be the responsibility of public-minded citizens and not exclusively that of the government. • The Lottery Committee commissioned a new map of the city so as to get a comprehensive picture of Calcutta. • Among the Committee’s major activities was road building in the Indian part of the city and clearing the riverbank of “encroachments”. • In its drive to make the Indian areas of Calcutta cleaner, the committee removed many huts and displaced the labouring poor, who were now pushed to the outskirts of Calcutta.
