Which one of the following is incorrect ?

The correct answer is (a). Fundamental Duties are not a part of Fundamental Rights.

Fundamental Rights are the basic rights and freedoms that are guaranteed to all citizens of India by the Constitution of India. They are enshrined in Part III of the Constitution. Fundamental Duties, on the other hand, are the moral obligations that every citizen of India has towards the nation. They are enumerated in Part IVA of the Constitution.

Article 51A of the Constitution lists 10 Fundamental Duties. These are:

1. To abide by the Constitution and respect its ideals and institutions, the National Flag and the National Anthem.
2. To cherish and follow the noble ideals which inspired our national struggle for freedom.
3. To uphold and protect the sovereignty, unity and integrity of India.
4. To defend the country and render national service when called upon to do so.
5. To promote harmony and the spirit of common brotherhood amongst all the people of India transcending religious, linguistic and regional or sectional diversities; to renounce practices derogatory to the dignity of women; and to value and preserve the rich heritage of our composite culture.
6. To protect and improve the natural environment including forests, lakes, rivers and wildlife and to have compassion for living creatures.
7. To develop scientific temper, humanism and the spirit of inquiry and reform.
8. To safeguard public property and to abjure violence.
9. To strive towards excellence in all spheres of individual and collective activity so that the nation constantly rises to higher levels of endeavour and achievement.
10. To provide opportunities for education and to promote adult education.

Fundamental Duties are not enforceable in a court of law. However, the State can take steps to promote awareness of Fundamental Duties and to encourage citizens to fulfill them.
