Will mark ! as the distance between an object and the center of the earth is increased, the object's mass decreases and its weight remains the same both the object's mass and its weight remain the same both the object's mass and its weight decrease the object's mass remains the same and its weight decreases

The object's mass remains the same and its weight decreases.

Explantion:

Mass is always constant, it never changes no matter the place or time. An object's mass is it's composition and is made of matter. Matter doesn't increase nor decrease.

Weight is a force. The gravitational pull multiplied by the mass is the weight. Since the mass is always constant, gravitational pull is what that changes. If the distance between an object and the centre of earth increases, it's like saying the object went farther away from the centre of earth. Now there is some gravitational pull on the object, but it's weak. The farther away you go from a source of gravity, the weaker will the pull be. Back to our scenario, the mass is constant but the gravitational pull decreases (weakens), so the weight decreases
