Not a fundamental duty: Abolition of titles except military and academic

Explanation:

The fundamental duties are a set of moral obligations that are listed in Part IV-A of the Indian Constitution. These duties were added through the 42nd Amendment Act in 1976 and serve as a reminder to citizens about their responsibilities towards the nation. They are not legally enforceable, but they are considered essential for the overall well-being and progress of society.

a) To abide by the constitution and respect the National Flag:
This is one of the fundamental duties mentioned in Article 51A(a) of the Indian Constitution. It emphasizes the importance of respecting and following the principles enshrined in the constitution, which is the supreme law of the land. By abiding by the constitution and respecting the National Flag, citizens show their allegiance to the nation and its values.

b) To promote harmony and brotherhood:
This is another fundamental duty listed in Article 51A(e) of the Indian Constitution. It highlights the significance of fostering a sense of unity and goodwill among all individuals irrespective of their religion, language, or region. Promoting harmony and brotherhood helps in maintaining social cohesion and prevents conflicts and divisions within society.

c) To uphold and protect the sovereignty:
Upholding and protecting the sovereignty of the country is a fundamental duty mentioned in Article 51A(c) of the Indian Constitution. It signifies the responsibility of citizens to safeguard the integrity, independence, and security of the nation. By being vigilant and actively participating in the democratic process, citizens contribute to the protection of the country's sovereignty.

d) Abolition of titles except military and academic:
This statement is not a fundamental duty. It does not appear in the list of fundamental duties provided in Article 51A of the Indian Constitution. However, it is important to note that the Indian Constitution does have provisions that discourage the conferment of titles, except for military and academic distinctions. This is mentioned in Article 18, which prohibits the state from conferring titles and honors.

In conclusion, the correct answer is option 'D' - Abolition of titles except military and academic. This statement does not fall under the category of fundamental duties, although the Indian Constitution discourages the conferment of titles in general through Article 18.
