Correct Answer: Gulf of Mannar

Solution : The correct answer is the Gulf of Mannar .

The Palk Strait serves as a significant waterway separating the southeastern coast of India, particularly Tamil Nadu, from the northern coast of Sri Lanka, near Jaffna. Close to Mannar Island, Sri Lanka, lies the Gulf of Mannar. These two water bodies, the Palk Strait and the Gulf of Mannar, are intricately linked by Adam's Bridge, also known as Rama Setu. This bridge, extending approximately 50 kilometres, serves as a geographical connection between the Indian and Sri Lankan landmasses.
