Explanation:

The first Chairperson of the Lokpal of India, an anti-corruption authority or body of ombudsmen, is **Justice Pinaki Chandra Bose**. He was appointed to this position in March 2019. Option (B) Tushar Mehta is the current Solicitor General of India, a legal advisor to the government. Option (C) Justice Sharad Arvind Bobde served as the 47th Chief Justice of India, not the Lokpal Chairperson. Option (D) Soma Roy Burman is a former Controller General of Accounts (CGA), a financial position, not related to the Lokpal. Therefore, Justice Pinaki Chandra Bose holds the distinction of being India's first Lokpal Chairperson.
