The correct answer is option 3, Indian Ocean. Sun da Trench is a deep underwater trench located in the Indian Ocean. To understand why this is the correct answer, let`s briefly discuss each of the other options.

Option 1, Atlantic Ocean, is incorrect because Sun da Trench is not located in the Atlantic Ocean. The Atlantic Ocean is the body of water that separates the Americas from Europe and Africa.

Option 2, Pacific Ocean, is also incorrect because Sun da Trench is not located in the Pacific Ocean. The Pacific Ocean is the largest ocean in the world and is located between the Americas and Asia.
