The correct answer is option 3, i.e., Eleven. The Indian Constitution includes eleven Fundamental Duties that are obligations of every citizen towards the nation. These duties were added to the Constitution through the 42nd Amendment Act in 1976. They are effectively moral and civic obligations meant to cultivate a sense of responsibility, patriotism, and respect for the ideals of the Constitution. Some of the fundamental duties include respecting the national flag and anthem, promoting harmony and the spirit of common brotherhood, safeguarding public property, protecting the natural environment, and striving towards excellence in different spheres of life. It is important for every citizen to be aware of and abide by these duties to contribute to the overall well-being and progress of the nation.
