The correct statement describing the relationship between the mass of two objects and their gravitational attraction is:
If the mass of one object increases while the mass of the other object remains the same, then the gravitational attraction increases.
Gravitational attraction is directly proportional to the product of the masses of the two objects, as described by Newton's law of universal gravitation. Therefore, increasing the mass of one object while keeping the other constant will result in an increase in gravitational attraction.
