Through the Forty Second Amendment to the Constitution of India, which of the following was/were inserted into its Preamble? 1. 'Liberty of thought, expression and belief' was substituted by 'Liberty of thought, expression, belief, faith and worship'. 2. The expression 'Unity of the Nation' was substituted by 'Unity and Integrity of the Nation'.

The 42nd Constitutional Amendment Act, 1976 modified the Preamble by inserting three new words — 'Socialist', 'Secular' and 'Integrity'. As a result, 'Sovereign Democratic Republic' became 'Sovereign Socialist Secular Democratic Republic', and 'Unity of the Nation' was substituted by 'Unity and Integrity of the Nation' (statement 2 is correct). Statement 1 is factually wrong: the original Preamble already used 'Liberty of thought, expression, belief, faith and worship'; this was not a 42nd Amendment substitution.
