According to the National Human Rights Commission Act, 1993, who amongst the following can be its Chairman?

Section 3 of the Protection of Human Rights Act and standard texts state that the NHRC Chairperson must be a senior Supreme Court jurist: traditionally a retired Chief Justice of India, and after the 2019 amendment, eligibility was widened to include persons who have been Judges of the Supreme Court as well [2]. The law therefore does not permit appointment of a serving Supreme Court or High Court judge, nor restrict the Chair solely to a retired High Court Chief Justice. Among the given choices, option 3 (Only a retired Chief Justice of India) best matches the original statutory requirement but is no longer exclusively correct after the 2019 amendment that added former Supreme Court judges to eligibility [3].
