10. Какой буквой на карте обозначена территория, относящаяся к Тихоокеанскому огненному кольцу?

The image shows a map with four labeled points: A, B, C, and D. The question asks to identify the letter representing the territory belonging to the Pacific Ring of Fire. The Pacific Ring of Fire is a horseshoe-shaped zone known for its seismic activity, located around the Pacific Ocean. Point B is located in the Pacific Ocean, near the coast of Asia and North America, which is characteristic of the Ring of Fire. Point A is in the Atlantic Ocean. Point C is in Africa. Point D is in North America, but not on the Pacific coast in a way that specifically denotes the Ring of Fire as a whole. Therefore, B is the most appropriate answer.
