Solution

The correct option is A At the centre of the Earth
The centre of gravity of the earth lies at the centre of the earth because the mass of the earth is equally distributed in all the directions about it. The earth is surrounded by the atmosphere with nearly equal thickness. Therefore, the centre of gravity of the atmosphere of the earth coincides with the centre of gravity of earth.
