Explanation:

• Secular word was added to Preamble to Indian Constitution by 42nd Constitutional Amendment Act of 1976.
• However, as the Supreme Court said in 1974, although the words ‘Secular state’ were not expressedly mentioned in the Constitution, there can be no doubt that Constitutionmakers wanted to establish such a state and accordingly Article 25 to 28 (guaranteeing the fundamental right to freedom of religion) have been included in the constitution.
• The Indian Constitution embodies the positive concept of secularism that is, all religions in our country (irrespective of their strength) shall have the same status and support from the state. (Hence option (b) is correct answer)
