Earth and the Sun would have greater gravitational attraction than the other options listed.
The gravitational attraction between two objects depends on their masses and the distance between them. The Sun is much more massive than the Earth, the Moon, a bouncy ball, or the planet Mercury. Therefore, the Earth-Sun gravitational attraction is the strongest of the options listed.
While the Earth-Moon gravitational attraction is significant and affects phenomena such as tides, the Sun's mass is about 27 million times greater than the Moon's mass. This means that the Sun's gravitational pull on the Earth is about 180 times stronger than the Moon's gravitational pull on the Earth.
