The correct statement that describes the relationship between the mass of two objects and their gravitational attraction toward each other is:
If the mass of one object increases while the mass of the other object remains the same, then the gravitational attraction increases.
According to Newton's law of universal gravitation, the gravitational force between two masses is directly proportional to the product of their masses. Therefore, if one mass increases while the other stays the same, the gravitational attraction will also increase.
