Assertion (A): The concept of the territory of India is broader than that of the Indian Union. Reason (R): In the territory of India, the territories of the states, the union territories, and such territories as may be acquired are mentioned in Article 1(2) of the Constitution.

Correct option is A

The Assertion (A) is correct because the term territory of India encompasses more than just the Indian Union. It includes the entire geographical area under India's control, which is broader. The term Indian Union refers specifically to the states and union territories within the geographical boundaries of India, but the territory of India can also include newly acquired territories, such as those acquired through treaties or wars.
The Reason (R) is also true. According to Article 1(2) of the Indian Constitution, the territory of India consists of:
1. The territories of the States.
2. The Union Territories.
3. Any territories that may be acquired.
Thus, the territory of India includes both the states and union territories, as well as any other territories that may be added to India. This makes the territory of India a broader concept compared to the Indian Union.
