The correct option is A Attorney-General for India
Article 76 and 78 deals with the Attorney General of India. The Attorney General of India is the highest law officer of the country. He is responsible to assist the government in all its legal matters. The President appoints the Attorney General (AG). The person who is appointed should be qualified to be appointed a judge of the Supreme Court. That means, he should be a judge of some high court for five years or an advocate of some high court for ten years.He has the right to speak or to take part in the meeting of any committee of the Parliament of which he is named as a member, but without a right to vote. Hence, Option A is correct. The rest of the persons are not bestowed with this power by the Constitution, hence, incorrect.
