Q. what was the exact constitutional status of India on 26th January, 1950

[A] A Democratic Republic

[B] A Sovereign Democratic Republic

[C] A sovereign Secular Democratic

[D] A sovereign Socialist secular Democratic Republic

Answer: B
Notes:

Ans) b 

Exp) Option b is correct. 

Why this question: Debate over the word ‘secular’ in the Preamble of the Constitution by fringe elements. 

The original Preamble, adopted by the Constituent Assembly on 26th November, 1949 and came into force on 26th January, 1950, declared India as a Sovereign Democratic Republic 

By the 42nd Amendment of 1976, enacted during the Emergency, the words Socialist and Secular were inserted. The Preamble now reads Sovereign Socialist Secular Democratic Republic.
