The correct statement describing 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.
This is consistent with Newton's law of universal gravitation, which states that the gravitational force between two objects is directly proportional to the product of their masses. If the mass of one object increases, the gravitational force between them also increases, assuming the other mass remains constant.
