Which of these island groups of India is located in the Arabian Sea?

Introduction / Context:
India has two major groups of islands: one in the Bay of Bengal and another in the Arabian Sea. Distinguishing between these two locations is a basic but important part of Indian geography. This question asks which of the listed island groups lies in the Arabian Sea rather than in the Bay of Bengal.

Given Data / Assumptions:

The options mention Andaman Islands, Nicobar Islands and Lakshadweep Islands, plus an all of the above option.

We are asked to identify which island group is located in the Arabian Sea.

We assume standard placement of Indian island territories on the map.

Concept / Approach:
The Andaman and Nicobar Islands lie in the Bay of Bengal and Andaman Sea to the south east of the Indian mainland. In contrast, the Lakshadweep Islands form an archipelago in the Arabian Sea to the south west of the mainland, off the coast of Kerala. Therefore, the correct approach is to recall that Lakshadweep belongs to the Arabian Sea, while Andaman and Nicobar belong to the eastern waters, and then choose Lakshadweep as the answer rather than all of the above.

Step-by-Step Solution:
Step 1: Visualise the map of India with the Bay of Bengal on the east and the Arabian Sea on the west.Step 2: Recall that Andaman and Nicobar Islands lie off the eastern coast in the Bay of Bengal and Andaman Sea, forming a long north south chain.Step 3: Remember that Lakshadweep is a cluster of small coral islands off the south western coast, in the Arabian Sea, closer to Kerala.Step 4: From this, identify Lakshadweep Islands as the only option that fits the Arabian Sea location.

Verification / Alternative check:
Looking at a map of Indian island territories, Andaman and Nicobar Islands are clearly shown to the south east of the mainland, labelled within the Bay of Bengal and Andaman Sea region. The Lakshadweep group, however, is represented by small dots to the south west in the Arabian Sea. None of the standard maps show all three groups in the Arabian Sea, so an all of the above answer would be incorrect. This visual confirmation reinforces that Lakshadweep is the correct choice.

Why Other Options Are Wrong:
The Andaman Islands are part of the Andaman and Nicobar union territory located to the east of mainland India in the Bay of Bengal, not in the Arabian Sea.
The Nicobar Islands form the southern part of the same union territory and also lie in the Bay of Bengal and Andaman Sea region.
All of the above cannot be correct because only Lakshadweep lies in the Arabian Sea, whereas Andaman and Nicobar are clearly in different waters on the opposite side of the peninsula.

Common Pitfalls:
Students sometimes remember that India has island groups on both sides but forget which name belongs where. They may also be tempted by the all of the above option without carefully thinking about the map. A good way to fix this in memory is to pair the names: Andaman and Nicobar with the Bay of Bengal to the east, and Lakshadweep with the Arabian Sea to the west. Once this pairing is clear, such questions become straightforward.

Final Answer:
The island group of India that is located in the Arabian Sea is the Lakshadweep Islands.
