Correct option is C
The Attorney General of India, as the chief legal advisor to the Government of India, can participate in the proceedings of either house of Parliament even though they are not a member of either house. This privilege is granted under Article 88 of the Indian Constitution, which allows the Attorney General to attend and speak in both the Lok Sabha and Rajya Sabha but not to vote. This provision is vital, as the Attorney General often needs to provide legal clarification on government policies, legislation, and matters related to constitutional law during parliamentary debates.
