Which set of factors allows earth to hold onto liquid water?

a. hydrogen bonds and distance from the sun
b. comet crashes and volcanic eruptions
c. moderate temperatures and strong gravity
d. strong magnetic fields and lunar tides

I believe the correct answer is C. The set of factors that would allow the Earth to hold onto water are the gravity and the temperature. Due to stronger pull of the gravity of Earth to water as compared to the gravity force pulled by the moon, water stays on Earth since Earth has a greater mass and nearer distance. Also, the temperature here on Earth allows water to stay as liquid rather than gas.
