I answer D
The pair of objects that would have the strongest gravitational pull is option C: two stars very far away from each other.
To understand why this is the case, we need to consider the principle of universal gravitation, formulated by Sir Isaac Newton. According to this principle, every object with mass exerts a gravitational force on every other object with mass.
The strength of the gravitational force between two objects depends on two factors: the masses of the objects and the distance between them. The greater the mass of an object, the stronger its gravitational pull. Conversely, the greater the distance between two objects, the weaker their gravitational pull on each other.
In option C, two stars being very far away from each other implies that the distance between them is significantly larger compared to the other options. Although the stars could potentially have different masses, the large distance between them increases the overall strength of their gravitational pull on each other. Therefore, option C would have the strongest gravitational pull.
