Statements 1,2 and 3 are correct.Under Article 120 of the Constitution, the business of the House is to be transacted in Hindi or in English, but a member who cannot adequately express himself in either of the two languages can, with the permission of the Speaker, address the House in any of the languages mentioned in the Eighth Schedule of the Constitution or in his mother tongue. The minutes and reports of the Parliamentary Committees are invariably prepared and presented to the house both in Hindi and in English.
