Final answer:
The question about Mount Everest's mass appears hypothetical since no scientific source provides an exact figure. The most plausible mass among the choices given would be 3.6×10²12 kg, but this is not a precise estimate.
Step-by-step explanation:
To answer the question about the mass of Mount Everest, we need to combine several areas of knowledge, particularly physics and a bit of geography. However, as no exact scientific sources give a definite mass for Mount Everest, we have to note that this question appears hypothetical and the provided choices may not represent real-world figures. Given the Earth's mass is approximately 5.972 × 10²24 kg, and knowing that nothing on Earth can compare to even a tiny fraction of the Earth's mass, options (b), (c), and (d) are unrealistic, providing masses too large in comparison. Option (a), with a mass of 3.6×10²12 kg, is the most plausible, albeit still not a precise scientific estimate. Moreover, measuring an object's mass on Earth in kg and then converting it into a fraction of the Earth's mass can lead to misunderstandings without the proper context of scale. The mass of real-world mountains depends on various factors, including their density and volume.
