The correct options are
A Inquiry into the violation of human rights
B Intervene in court proceedings related to human rights
C Promote research in the field of human rights
Some of the functions of the NHRC are inquiry into the violation of human rights, intervention in court proceedings relating to human rights, promotion of research in the field of human rights, engagement in human rights education and encouraging the effects of NGOs and institutions working in the field of human rights. However, the NHRC has no right to punish the culprit.
