Identifying Social Reformers Against Religious Orthodoxy

The question asks to identify Indian social reformers active during British Rule who opposed religious orthodoxy. We need to evaluate the contributions of each individual listed:

• Ishwar Chandra Vidyasagar (A): A prominent figure who championed widow remarriage and opposed child marriage, directly challenging entrenched religious and social customs.
• Raja Ram Mohan Roy (C): Considered a pioneer of modern India, he founded the Brahmo Samaj and fiercely advocated against practices like Sati and caste discrimination, fundamentally challenging religious orthodoxy.
• Bhartendu Harishchandra (B): While a significant social and literary figure, his primary focus wasn't solely on opposing religious orthodoxy in the same manner as Vidyasagar or Roy.
• Lala Lajpat Rai (D): Primarily known as a nationalist leader focused on political reform and Swaraj.
• Vinoba Bhave (E): A post-independence leader, renowned for the Bhoodan movement, whose main focus was socio-economic reform rather than challenging religious orthodoxy during the specified period.

Selected Reformers

Based on their direct and significant actions against religious orthodoxy during the British Rule era, Ishwar Chandra Vidyasagar (A) and Raja Ram Mohan Roy (C) are the most fitting choices.

Therefore, the correct option includes A and C only.
