The Constitution of India

  Option 1 is the correct answer.

The Indian Constitution exhibits federal characteristics (division of powers between Union and States, independent judiciary, written constitution, rigidity) but contains unitary features (single citizenship, strong center during emergencies, flexible amendment process, directive principles). Dr. Ambedkar described it as 'quasi-federal' - federal in form but unitary in spirit.

Dr. Rajendra Prasad was elected the first President of India in 1950 by an electoral college consisting of members of the Constituent Assembly (who also served as the provisional parliament). This election occurred under the transitional provisions of the Constitution before the first general elections of 1951-52 established the regular electoral college.

The Preamble begins with the words “We the people of India…” Thus, it is clearly indicating the source of all authority of the constitution. Hence, option (4) is the correct answer.

The main function of the 'Constituent Assembly' was framing the constitution.
