Given Two Objects of the Same Mass, One at Sea

Given two objects of the same mass, one at sea level, and the other atop Mount Everest, which has the greater weight?

A) the object on Mount Everest because the distance to the center of Earth, and therefore, the mass of Earth is locally greater
B) the object at sea level because the distance to the center of Earth is least from this elevation
C) the object at sea level because the centrifugal force is greatest at sea level
D) the object on Mount Everest because centrifugal force increases with distance from the center of gravity
E) the object on Mount Everest because the Coriolis effect is strongest at high altitudes
