The correct answer is option 3, the Atlantic Ocean. The shape of the Atlantic Ocean is often compared to the English alphabet "S" because of its curved, winding shape. It stretches from the east coast of North America to the west coast of Africa and South America, forming an "S" shape when viewed on a map. The Arctic Ocean, option 1, is located in the northernmost part of the Earth and doesn`t have an "S" shape. The Indian Ocean, option 2, is located between Africa, Asia, and Australia, and also does not have an "S" shape. The Pacific Ocean, option 4, is the largest and deepest ocean in the world, but it does not have the characteristic "S" shape. Therefore, option 3, the Atlantic Ocean, is the correct answer.
