Option a is the correct answer. Dakshinamurti means "the one who faces south", and depicts Shiva as a teacher of yoga, music, and wisdom. The idol of Dakshinamurti shows him sitting under a banyan tree, with his right leg resting on a dwarf, who represents ignorance and illusion. His right hand shows the chin mudra, which means "the gesture of consciousness", and signifies the union of the individual and the universal self. His left hand holds a fire pot, which represents the fire of knowledge that burns away ignorance. Around him are four sages, who are his disciples and listen to his teachings .
