Step 1: Understanding the Question:
The question asks for the comprehensive meaning of "Secularism" as it is practiced and understood in India.
Step 2: Key Concept:
Indian secularism is a positive concept, which is different from the Western model of strict separation between state and religion. The Indian concept is based on 'Sarva Dharma Sama Bhava' (equal respect for all religions).
Step 3: Detailed Explanation:
Let's analyze the options in the Indian context:
(A) Indian has religious diversity: While this is a fact about Indian society, the principle of secularism is the constitutional and political response to manage and cherish this diversity. So, it is intrinsically linked.
(B) Indian has no state religion: This is a fundamental aspect of Indian secularism. The State does not uphold any particular religion as the official state religion.
(C) There is equal respect for all religions in India: This is the positive connotation of Indian secularism. The state not only tolerates all religions but also gives them equal respect and protection.
All three statements are correct facets of the Indian concept of secularism. The term encompasses the absence of a state religion, the principle of treating all religions equally, and is a framework for managing religious diversity. Therefore, 'All of these' is the most appropriate answer.
Step 4: Final Answer
All the given options correctly express different dimensions of the meaning of secularism in the Indian context. Hence, the correct answer is (D).
