Which of the following ocean trenches are **not** located in the Pacific Ocean? 1. Bonin Trench 2. Cayman Trench 3. Kermadec Trench 4. South Sandwich Trench Select the answer using the code given below.

The Bonin Trench (also known as the Izu-Bonin or Izu-Ogasawara Trench) is located in the western Pacific Ocean, stretching from Japan toward the Mariana Trench. The Kermadec Trench is also situated in the South Pacific Ocean, formed by the subduction of the Pacific plate. In contrast, the Cayman Trench (or Cayman Trough) is located in the western Caribbean Sea, which is part of the Atlantic Ocean basin. The South Sandwich Trench is located in the South Atlantic Ocean, near the boundary with the Southern Ocean [1]. Therefore, the Bonin and Kermadec trenches are in the Pacific, while the Cayman and South Sandwich trenches are not. This makes options 2 and 4 the correct selection for trenches not located in the Pacific Ocean.
