Which artist is considered as a tantric painter?

G.R. Santosh

The correct answer is Option 3- G.R. Santosh

In the 1960s, Biren De and G. R. Santosh in Delhi and K. C. S. Paniker in Madras moved in this direction when they turned to the past and local artistic traditions to create a unique Indian abstract art. This style became successful in the West and later in India and came to be known as Neo-Tantric art because of its use of geometrical designs seen in traditional diagrams for meditation or yantras.
