The paintings of Abanindranath Tagore are best classified as revivalistic, hence option 3 is the correct answer. To understand this, one has to delve into the characteristics of all four available options. Realistic paintings are those that represent subject matter truthfully, which does not fully encompass Tagore`s work. Socialistic paintings are tied closely to socialist politics and ideology, which is not a primary feature of his artwork. Impressionistic paintings are characterized by small, thin, yet visible brush strokes, open composition and an emphasis on accurate depiction of light in its changing qualities. However, revivalistic is the most fitting description for Tagore`s work. He is known for modernising Mughal and Rajput styles, effectively creating an "Indian" style that parted with the Western realism introduced during the colonial era. This is what is meant by revivalistic art – it`s about reviving and modernising traditional art styles, which clearly aligns with Tagore`s paintings.
