Final answer:
The correct answer is Mount Chimborazo, as it is a 3000 m high mountain located on the equator. Mount Everest, while being the tallest mountain above sea level, is not on the equator. The correct answer is D.
Step-by-step explanation:
Mount Kilimanjaro is in Africa near the equator but doesn't meet the specified height in the question.
The student asked about a 3000 m high mountain located on the equator. From the given options, the correct answer is Mount Chimborazo. It is not as tall as Mount Everest, which is the tallest mountain on Earth with a peak at 29,029 feet or approximately 8,848 meters. Although Mount Everest is the tallest mountain above sea level, Mount Chimborazo's peak is the furthest point from the center of the Earth due to the equatorial bulge. Therefore, when considering the height above Earth's core, Mount Chimborazo is the highest.
Mount Kilimanjaro is the highest mountain in Africa, located near the equator, and it has an elevation of 19,340 feet, or about 5,895 meters. However, it falls short of the 3000 meters mentioned in the question (which seems likely a typo for '30000 m'). Mount McKinley, also known as Denali, is the highest peak in North America but is not located on the equator.
