Option 1 -> Bay of Bengal is part of the Indian Ocean, not a separate connection made by Palk Strait.
Option 2 -> Arabian Ocean is on India's west coast; Palk Strait is on the east coast between India and Sri Lanka.
Option 3 -> Gulf of Aden and Red Sea are located near the Arabian Peninsula and Africa, completely unrelated to Palk Strait.
Option 4 -> Palk Strait lies between India and Sri Lanka, connecting Gulf of Mannar to the southwest with Palk Bay (Bay of Bengal) to the northeast.
Hence, Option 4: Gulf of Mannar and Bay of Bengal -> The Palk Strait is a narrow channel between Tamil Nadu (India) and Sri Lanka's northern province, serving as the geographical link between these two water bodies -> correct
