Correct Answer: (e) None of the above/More than one of the above
Solution:The Attorney-General Can participate in the proceedings of any house of Parliament as a non-member. There is also a Vice-president in the given option and he is also not a member of Parliament, so here, the Vice-President can also be the answer. However, if the motion to remove the Vice-President from the post of chairman of Rajya Sabha is under consideration in the house, then the Vice-President does not remain the ex-officio chairman of Rajya Sabha at that time. During this time, he can be a part of the House and in this context, he can speak in the house. If, it is a matter of Participation in the proceedings of both Houses of the Parliament, then the Attorney-General will be there because the Vice-President Participates only in the Rajya Sabha.
