As a Non-Member who can participate in the proceedings of either House of Parliament.

Correct answers: (a) Vice-President or (c) Attorney General

Explanation

Neither the Vice-President nor the Attorney-General is a member of Parliament, yet both take part in its proceedings. The Vice-President presides over the Rajya Sabha as its ex officio Chairman. Under Article 88, the Attorney-General has the right to speak in either House, in a joint sitting and in any parliamentary committee of which he is named a member, but not to vote. So the answer key accepts both (a) and (c). Strictly, only the Attorney-General takes part in the proceedings of both Houses.
