Exp) Option c is the correct answer.

Option c is correct. The main characteristic of the Parliamentary form of government is that the executive remains responsible to the legislature for its policies and acts. The ministers are collectively responsible to the Parliament in general and to the Lok Sabha in particular. The principle of collective responsibility implies that the Lok Sabha can remove the council of ministers headed by the prime minister from office by passing a vote of no confidence.

Important Tips

• The parliamentary system is based on the principle of co-operation and co-ordination between the legislative and executive organs. Whereas the presidential system is based on the doctrine of separation of powers between the two organs.
• In the parliamentary system of government, there is a lack of continuity of policies. The parliamentary system is not conductive for the formulation and implementation of long-term policies owing to the uncertainty of the tenure of the government. A change in the ruling party is usually followed by changes in the policies of the government.
• The Prime Minister can be changed without election if the Members of the Lok Sabha of the majority party choses another person to be its leader and thus the Prime Minister.
