Solution

The correct option is C $M_{m} = M_{e}$
Gravitational mass is measured by comparing the force of gravity of an unknown mass to the force of gravity of a known mass. This is typically done with some sort of balance scale. The beauty of this method is that no matter where, or what planet, you are, the masses will always balance out because the gravitational acceleration on each object will be the same.

Q. The minimum speed with which a body is projected from the surface of the earth so that it reaches to the surface of the moon is v while the minimum speed with which a body is projected from the surface of the moon so that it reaches to the surface of the earth is v'. Then, disregarding the spinning and orbital motions of the earth and the moon, and using the fact that

\frac{M_{E}}{R_{E}} > \frac{M_{M}}{R_{M}}

where

M_{E}, M_{M}, R_{E}

and

R_{M}

are mass of earth, mass of moon, radius of earth and radius of the moon respectively, we can say that :
