Answer:
A and D.
Step-by-step explanation:
According to Newton's law of gravitation, the force of gravitation depends on the mass of the two bodies and square of distance between them.

G is the gravitational constant.
As one moves to higher altitude, force of gravity decreases because distance increases. So, option A is correct.
As one gains mass, the force of gravity on him increases. So, option D is correct.
The force does not depend on the speed of the body.
