Explanation: 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. Each of these groups contains numerous smaller islands, many of which are uninhabited.
Havelock Island, Neil Island, and Ross Island are all part of the Andaman Islands. Havelock Island is known for its beautiful beaches and is a popular tourist destination. Neil Island is also a tourist destination, famous for its natural beauty and beaches. Ross Island, historically significant as the administrative center during the British colonial period, is now a tourist attraction.
Alexandera, however, is not an island but a town located on the Great Nicobar Island, which is the largest island in the Nicobar group. It serves as the administrative headquarters for the Nicobar Islands. This makes Alexandera the odd one out in the list, as it is a town rather than an island.
Understanding the geographical layout and the classification of the Andaman and Nicobar Islands is crucial for identifying the correct answer. The key to solving this question is recognizing that Alexandera is a town and not an island, distinguishing it from the other options which are all islands within the Andaman and Nicobar Islands.
This question tests the ability to differentiate between islands and towns within the Andaman and Nicobar Islands, as well as the geographical knowledge of the region. It is important to be familiar with the specific names and classifications of the islands and towns within this union territory to avoid common misconceptions and to correctly identify the odd one out.
