Statement 1: Parliament can enforce some Fundamental Duties through legislation (e.g., laws protecting the environment, national symbols). Thus, this statement is incorrect. Statement 2: Fundamental Duties are listed in Part IVA of the Constitution and are explicitly applicable only to citizens of India. This statement is correct. Statement 3: The Fundamental Duties encompass various obligations that can be broadly classified as moral duties (e.g., cherishing ideals) or civil duties (e.g., respecting the Constitution, protecting public property). This statement is generally considered correct. Statement 4: Paying taxes is a legal duty imposed by tax laws, not one of the Fundamental Duties listed in Article 51A. Thus, this statement is incorrect.
