The correct answer is option 4: Twenty-five Parts. The Indian Constitution is divided into different parts to cover various aspects of governance and law. Each part deals with a specific topic or subject. Some of the important parts include Part I: Union and its Territory, Part III: Fundamental Rights, Part IV: Directive Principles of State Policy, Part IX: Panchayats, and Part XI: Relations between the Union and the States. It is important to note that the number of parts does not necessarily indicate the importance or significance of a particular topic. It is crucial to have a thorough understanding of all the parts to comprehend the Indian Constitution comprehensively.
