In the question below, is given a statement followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the suggested courses of action logically follow (s) for pursuing. Statement: The numbers are impressive. In its quest towards Swachh Bharat, the government has built 4.98 crore rural household latrines in the last three years. What's more, recent surveys by the NSSO and the Quality Council of India show that over 90% people with access to toilets are using them. Launched with the idea of Clean India, it is expanding from urban to the rural areas and is spreading awareness among the masses. Courses of action: I. Given that most rural areas in India lack proper drainage and a sewage network, the government has focused on building twin-pit toilets. But there is no data on whether the size of hastily built twin pits takes into account the number of users, and whether each pit is enough to collect waste for three years.  II. While this is a positive indicator, there are many other areas that need attention such as the shortage of water, sensitization of citizens, proper maintenance and usage of toilets, and overcoming the resistance to dry manure made from human waste.  III. One of the biggest challenges for Swachh Bharat in rural areas is managing liquid waste, which pollutes natural water bodies. Though the scheme covers this aspect as well, the immediate focus is to deal with open defecation.
