Match List-I with List-II and select the answer using the code given below the Lists : List-I List-II (Island / Nation) (Tectonic Plate) A. Comoros 1. North American Plate B. Baffin Island 2. African Plate C. Sri Lanka 3. Eurasian Plate D. Andaman Islands 4. Indo-Australian Plate Code : A B C D
Explanation
The matching of islands to their respective tectonic plates is as follows: Comoros is located in the Indian Ocean off the coast of East Africa and sits on the African Plate [4]. Baffin Island, part of the Canadian Arctic Archipelago, is situated on the North American Plate. Sri Lanka is geologically part of the Indo-Australian Plate, specifically the Indian portion [5]. The Andaman Islands are located at the convergent boundary where the Indo-Australian Plate subducts beneath the Eurasian Plate (specifically the Burma microplate) [5]. While the Andaman Islands are often associated with the boundary zone, in standard geographical matching for competitive exams, they are categorized under the Eurasian Plate due to their position on the overriding plate side of the subduction arc. Therefore, the correct sequence is A-2, B-1, C-4, D-3.
