1. An object's mass is the same everywhere in the universe.

2. A person's weight changes depending on where they live.

3. The terms "mass" and "weight" do not refer to the same thing.

The mass of an object is the same everywhere in the universe since it is unaffected by other factors, hence the mass of a body is unaffected by its location.

As a result, the statement (a) is incorrect.

The weight of a body varies from location to place due to the following relationship between mass and gravitational acceleration.

$W=m脳g$

Because gravity's acceleration changes from place to place in the universe, a body's weight should be determined by its position.

As a result, the assertion (b) is correct.

Because the mass of a body is the same everywhere in the universe, but the weight of a body changes from place to place due to variations in acceleration, the terms mass and weight are not interchangeable

As a result, statement (c) is untrue.
