Science ( Need help really bad Please!)

An object's weight is dependent upon its location in the universe. Why is this true?

A.
This is true because weight is the magnitude of gravitational force acting on an object, and since gravitational force varies in different places in the universe, weight also varies.

B.
This is true because weight is the amount of matter in an object. Because gravity is a force, and force is proportional to weight, both gravity and weight vary in different places in the universe.

C.
This is true because gravitational force is the magnitude of weight acting on an object and since weight varies in different places in the universe, gravitational force also varies.

D.
This is true because gravitational force is the magnitude of weight acting on an object's mass and since weight varies in different places in the universe, both gravitational force and mass also vary.

  2. F = m g
    or
    Weight = mass * acceleration of gravity

    m is mass, sometimes in kilograms. It is the same everywhere and depends only on which proton and neurons are there and how many.

    g is the acceleration of gravity. On earth it is about 9.81 meters/second^2
    On the moon for example it is only about 1/6 as strong.

    In other words, A
