The correct option is D The government bears a part of the cost and reduces the load on commoners.
In India, the government has taken up public sector activities so that the services remain affordable to the weak and the marginalised section of the society. If the private sector takes up these services, the basic necessities will become expensive.
It is important that the government pays special attention to the marginalised and the vulnerable sections of the society by facilitating basic necessities and by improving the quality of services rendered to them.
