EXPERT PLS SEND ANSWER, URGENT!!!

Solution,
Acceleration due to gravity is defined as:
$$\begin{gathered} g=\frac{GM}{R^2} \\ where, \\ M is the mass of the earth \\ R is the radius of the earth \\ G is the gravitational cons\tan t \end{gathered}$$
Thus,
the acceleration due to gravity is independent of the mass of the body.
Also,
Acceleration due to gravity depends on the mass of the earth.
Acceleration due to gravity decreases both with altitude and with depth into the earth.
So,
CORRECT option is (4)
