Explanation: The Andaman and Nicobar Islands are a union territory of India, located in the Bay of Bengal. They consist of two distinct groups of islands: the Andaman Islands and the Nicobar Islands. The Andaman Islands are located to the north, while the Nicobar Islands are to the south. This geographical arrangement is crucial for understanding the location and classification of the islands.
Katchall is an island that belongs to the Nicobar group of islands, not the Andaman group. This is a common misconception among students, as the Andaman and Nicobar Islands are often collectively referred to, leading to confusion about which islands belong to which group. Katchall is located in the southern part of the Nicobar Islands, making it part of the Nicobar group.
Nancowry, on the other hand, is indeed an island in the Nicobar group. It is one of the larger islands in the Nicobar group and is known for its strategic importance and natural beauty. The Nicobar Islands are characterized by their tropical climate and diverse flora and fauna, making them a unique part of the Indian subcontinent.
The confusion in the question arises from the incorrect statements about the geographical arrangement of the Andaman and Nicobar Islands and the incorrect classification of Katchall. The correct statement is that Nancowry is an island in the Nicobar group, which is why option C is the correct answer.
Understanding the geographical layout and the classification of the islands is essential for students preparing for competitive examinations, especially those related to geography and general knowledge. It is important to remember that the Andaman Islands are to the north, and the Nicobar Islands are to the south, and to correctly identify which islands belong to which group.
