• Article 29(1) provides that any section of the citizens residing in the territory of India or any part thereof having a distinct language, script or culture of its own shall have the right to conserve the same.
• Article 347 of the Constitution states that on a demand being made in that behalf the President may, if he is satisfied that a substantial proportion of the population of a State desire the use of any language spoken by them to be recognized by that State, direct that such language shall also be officially recognized throughout that State or any part thereof for such purpose as he may specify.
• Article 350B provides that there shall be a Special Officer for linguistic minorities to be appointed by the President. Hence only statements 1&2 are correct.
