This question is asking us which mountain is the tallest in the world. We are given four options to choose from. Option A is Everest, Option B is Kilimanjaro, Option C is Elbrus, and Option D is lanc. The correct answer is Option A, which is Everest. Everest is located in the Himalayas, which are a range of mountains in Asia. It is the highest mountain in the world, with a peak that reaches 8,848 meters above sea level. Kilimanjaro, Elbrus, and lanc are also mountains, but they are not as tall as Everest. Kilimanjaro is located in Tanzania, Elbrus is in Russia, and lanc is in Nigeria.
