- Statement 1: Article 343(1) of the Constitution states that the official language of the Union shall be Hindi in Devanagari script. This is correct. - Statement 2: Article 345 allows the Legislature of a State to adopt any one or more of the languages in use in the State or Hindi as the language(s) for official purposes. The Constitution does not specify the official languages for states; it empowers the states to choose them. This statement is incorrect. - Statement 3: Article 348(1) mandates that all proceedings in the Supreme Court and in every High Court shall be in the English language, unless Parliament provides otherwise by law (or the Governor, with President's consent, authorizes Hindi or other official language for High Court proceedings, but judgments, decrees, orders must still be in English unless translated). The default is English, and this holds true "until Parliament provides otherwise". This statement is correct.
