The correct choice is: “Justice Arun Mishra”

Former Supreme Court judge Justice Arun Kumar Mishra was appointed Chairperson of the National Human Rights Commission (NHRC) on 2 June 2021, the post having been vacant since Justice H. L. Dattu completed his term in December 2020. Under the Protection of Human Rights Act, 1993 (as amended in 2019), the Chairperson must be a person who has been Chief Justice of India or a judge of the Supreme Court, which is how a former puisne judge became eligible.

“Justice Dattu” (H. L. Dattu, 2016–2020) was his predecessor; “Justice Verma” (J. S. Verma) headed the NHRC from 1999 to 2003; “Justice Bobde” (S. A. Bobde) was Chief Justice of India until April 2021 and never headed the NHRC.
