The correct answer is option 2: Mariana Trench. The Mariana Trench is the deepest surface depression on Earth. It is located in the western Pacific Ocean and reaches a depth of about 36,070 feet (10,994 meters) at its lowest point, known as the Challenger Deep. The trench is formed by the collision of two tectonic plates, where one plate is forced beneath the other in a process known as subduction. As a result, the Mariana Trench has steep sides and is home to unique and diverse forms of marine life that have adapted to the extreme conditions. The other options, Kurile Trench, Tonga-Kermadec Trench, and Bentley Subglacial, are not as deep as the Mariana Trench.
