Concept:Indian secularism implies equal respect and treatment for all religions by the state.
Explanation:The 42nd Amendment, 1976, added the words "Secular", "Socialist", and "Integrity" to the Preamble of the Constitution.
India was declared a "Sovereign, Socialist, Secular, Democratic Republic".
The Latin word "seculum" means an age or the present age, from which the term "secular" is derived.
In the Indian context, secularism means "Dharmanirapaksata" or impartiality towards religion.
It also means "Sarva Dharma Samabhava" or equal respect for all religions.
A secular state does not identify itself with any particular religion.
It protects all faiths unless they threaten the unity and integrity of the country.
Hence, uniform treatment of all religions is the most essential feature of Indian secularism.
Answer:Option B: Uniform treatment of all religions by the state.
