Both A and B are correct because according to Newton's law of universal gravitation, the force between two masses is directly proportional to the product of their masses. Therefore, if the Sun's mass were doubled, its gravitational pull on Earth would double, and conversely, Earth's gravitational pull on the Sun would also double.
