Detailed Solution
The correct matching is Pacific–Mariana Trench, Arctic–Molloy Deep, Indian–Sunda Trench and Atlantic–Puerto Rico Trench.
The Mariana Trench is situated in the western Pacific Ocean. It contains the Challenger Deep, which has a measured depth of about 10,935 metres and is the deepest known point in the world's oceans.
The Molloy Deep lies in the Fram Strait region between Greenland and Svalbard and is regarded as the deepest known region of the Arctic Ocean. Its maximum depth is approximately 5,500–5,600 metres.
The Sunda Trench, whose eastern part is also called the Java Trench, lies in the eastern Indian Ocean south of Indonesia. Modern bathymetric surveys have confirmed the deepest region of the Indian Ocean within this trench system at a depth of about 7.2 km.
The Puerto Rico Trench, located near the boundary between the Caribbean Sea and the Atlantic Ocean, is the deepest trench system of the Atlantic Ocean. Its depth exceeds 8,400 metres.
