Consider the following statements: 1. The Constitution of India has 20 parts. 2. There are 390 articles in the Constitution of India in all. 3. Ninth, Tenth, Eleventh and Twelfth Schedules were added to the Constitution of India by the Constitution (Amendment) Acts. Which of the statements is/are correct?

Statements 1 and 2 are incorrect. The original Constitution contained 395 Articles divided into 22 Parts (not 20) and 8 Schedules; later amendments increased the number of parts and articles [1]. Hence statement 1 (20 Parts) and statement 2 (390 Articles) are wrong. Statement 3 is correct: the Ninth, Tenth, Eleventh and Twelfth Schedules were not in the original text but were added subsequently by Constitution (Amendment) Acts. These schedules deal with validation of certain laws (Ninth), anti‑defection (Tenth), Panchayats (Eleventh) and Municipalities (Twelfth) [1]. Therefore the correct choice is option 3.
