Why Correct: Raja Ravi Varma was a pioneer of modern Indian painting known for realistic oil paintings and lithographs, but he was not associated with the Bengal School of Art, which was a nationalist revivalist movement centred in Calcutta.
Distractor Analysis: Nandalal Bose was a principal disciple of Abanindranath Tagore and a leading figure of the Bengal School. Abanindranath Tagore founded the Bengal School. Sunayani Devi, a sister of Abanindranath, was also associated with the Bengal School.
Takeaway: The Bengal School rejected Western academic realism; Raja Ravi Varma's style is the opposite. This contrast is a common exam point.
