Explanation: The Andaman and Nicobar Islands are a group of islands located in the northeastern part of the Indian Ocean, forming a Union Territory of India. This archipelago is situated in the Bay of Bengal and is composed of 572 islands, of which only 38 are inhabited. The islands are divided into two main groups: the Andaman Islands to the north and the Nicobar Islands to the south.
The Andaman and Nicobar Islands are significant for several reasons. Geographically, they are located at a strategic point between the Indian subcontinent and Southeast Asia, making them important for India's maritime security and trade routes. The islands are also known for their rich biodiversity, with a variety of flora and fauna, including several endemic species. The Andaman and Nicobar Islands are home to several indigenous tribes, such as the Sentinelese, who have maintained a largely isolated lifestyle.
The islands have a unique administrative status as a Union Territory, which means they are directly governed by the central government of India. This status allows for special provisions and governance tailored to the unique needs of the islands. The Union Territory of Andaman and Nicobar Islands has its own legislative assembly and a lieutenant governor appointed by the President of India.
In contrast, the other options provided (Hydra, Euboea, and Chios) are Greek islands located in the Aegean Sea and are not part of the Indian Union. These islands are part of Greece and have no connection to India's geographical or administrative territories.
Understanding the geographical and administrative status of the Andaman and Nicobar Islands is crucial for comprehending India's territorial composition and its strategic importance in the Indian Ocean region. This knowledge is essential for students preparing for competitive examinations that cover Indian geography and political administration.
