Correct Option
According to Section 3(2) of the Protection of Human Rights Act, 1993, the Chairperson of the National Human Rights Commission (NHRC) shall be a person who has been a Chief Justice of India. The appointment is made by the President of India based on the recommendation of a committee. This committee comprises the Prime Minister (Chairperson), the Speaker of the Lok Sabha, the Union Minister of Home Affairs, the Leaders of the Opposition in both Houses of Parliament, and the Deputy Chairperson of the Rajya Sabha.
Incorrect Options
Options (a) and (b) are incorrect. The Protection of Human Rights Act, 1993, specifies that only a retired Chief Justice of India is eligible for the post of Chairperson of the NHRC, thereby excluding serving judges of the Supreme Court or High Court.
Option (d) is incorrect. While a retired Chief Justice of a High Court is eligible to be appointed as a member of the NHRC, they are not eligible to serve as its Chairperson. The Act clearly distinguishes the eligibility criteria for the Chairperson and other members.
