A. Atlantic Ocean
B. Pacific Ocean
C. Indian Ocean✓ Correct Answer
D. Arctic Ocean
💡 Solution & Explanation
The Laccadive-Chagos Ridge is a prominent north-south trending submarine volcanic ridge situated in the central Indian Ocean, supporting island chains such as the Maldives and the Chagos Archipelago. It was formed as the Indian tectonic plate moved northward over the Réunion hotspot during the Cenozoic era. The Atlantic Ocean features the Mid-Atlantic Ridge rather than this specific Indian Ocean feature. Submarine ridges in the Pacific include the Ninety East Ridge and the Emperor Seamount Chain.
