Explanations:The Andaman and Nicobar Islands are a group of islands located in the Bay of Bengal, forming a union territory of India. The islands are divided into two main groups: the Andaman Islands and the Nicobar Islands. The Andaman Islands are located to the north, while the Nicobar Islands are located to the south. This geographical layout is crucial for understanding the correct answer to the question.
Let's analyze each statement individually:
Statement 1: "Katchall is part of the Andaman group of islands." This statement is incorrect. Katchall is actually part of the Nicobar group of islands, not the Andaman group. The Nicobar Islands are a collection of islands located to the south of the Andaman Islands, and Katchall is one of the islands in this group.
Statement 2: "The Andaman is in the south and Nicobar is in the north." This statement is also incorrect. The correct geographical layout is that the Andaman Islands are located to the north, and the Nicobar Islands are located to the south. This is a common misconception that can lead to confusion when answering questions about the Andaman and Nicobar Islands.
Statement 3: "Nancowry is an island in the Nicobar groups." This statement is correct. Nancowry is indeed an island in the Nicobar group of islands. The Nicobar Islands include several islands, and Nancowry is one of them.
Given these analyses, the only correct statement is Statement 3. Therefore, the correct answer is Option C, which states that only Statement 3 is true.
Understanding the geographical layout and the grouping of the islands is essential for correctly answering questions about the Andaman and Nicobar Islands. It is important to remember that the Andaman Islands are located to the north, and the Nicobar Islands are located to the south. Additionally, it is crucial to know which islands belong to which group to avoid common misconceptions.
