The correct answer is - C. Mount Everest.
Mount Everest is the highest mountain in the world if we go by measuring the height from the sea level, and it is 8848 meters high. It is estimated that it is growing in height by around 8 cm annually, so for the time being it is becoming even bigger and bigger every year. Mount Everest lies on the border between Nepal and China, and its summit point is actually the border between the two countries. In the local languages it is known by the name Sagarmatha, in Nepali, and Chomolungma, in Tibetan.
