Correct option is C
The term Union in the phrase “Union of States” in the Indian Constitution is derived from the Canadian Constitution. The framers of the Indian Constitution drew inspiration from multiple sources around the world, and the concept of a Union was particularly borrowed from Canada, which describes itself as a "Dominion" or "Union" of provinces. This concept emphasizes that India is an indestructible union of states, meaning that states cannot secede from the Union, just as provinces in Canada cannot secede from the country. This formulation was chosen to reflect the strong central structure of the Indian state while accommodating regional diversity.
