The correct answer is option 4, Adult franchise. The Preamble to our Constitution is an introductory statement that outlines the objectives and guiding principles of our Constitution. It does not explicitly mention adult franchise, which refers to the right to vote for all adults. However, it does mention other values and goals, such as justice, fraternity, and equality of status. Justice refers to the fair treatment of individuals and the promotion of social justice. Fraternity emphasizes the spirit of brotherhood and unity among all citizens. Equality of status refers to the idea that all individuals are equal before the law. While adult franchise is an important aspect of our democratic system, it is not specifically mentioned in the Preamble.
