Use the data table to answer the following question. Which one of the following answers is the best explanation as to why the gas giant planets have so many moons as compared to the inner planets?

• Comets originate in the areas around the gas giants, therefore they pull in moons.

• The gas giant planets have a stronger gravitational pull capable of holding more moons.

• The inner planets have more mass, therefore cannot keep the moons in orbit.

• The gas giants are farther from the sun, therefore they have the most gravity.
