The correct option is C Shankaracharya
Sankaracharya was born in Kaladi, Kerala and he propounded the Advaita Vedanta philosophy (strict monism). According to him, there are various levels of truth: on the everyday level, the world was produced by Brahma. But on the highest level of truth, the whole universe, along with the Gods is Maya (illusion). The only ultimate reality was Brahman, the impersonal world soul, who is one without a second.
