Explanations:Union Territories in India are administrative divisions that are directly governed by the Union Government. They do not have their own state government and are managed by the central government through an appointed administrator. Among the Union Territories, some are located on the mainland, while others are island groups.
Andaman and Nicobar and Lakshadweep are the two Union Territories that are island groups. Andaman and Nicobar is a group of islands located in the Bay of Bengal, while Lakshadweep is a group of islands located in the Arabian Sea. These island groups are unique in their geographical location and are distinct from other Union Territories such as Chandigarh, which is a landlocked territory.
Chandigarh, on the other hand, is a Union Territory located in the northern part of India, bordering the states of Punjab and Haryana. It is not an island group but rather a city that serves as the capital of both Punjab and Haryana. Therefore, it is not included in the list of island groups.
Understanding the geographical nature of each Union Territory is crucial for correctly identifying which ones are island groups. This knowledge is particularly important for competitive examinations where questions on Indian geography and administrative divisions are common.
