I'm not sure but i would say C.storing the heat energy.
Answer:
Ionization energy, electronegativity, and lattice energy are the factors that influence the formation of ionic bonds of elements.
The higher levels of gravity put on an object the more weight the object has. For example someone who weighs say 100 lbs would weigh more if higher amounts of gravity would be applied to them. And less if less gravity was applied. But larger objects will automatically have more gravity applied to them than something smaller due to the gravitational pull needing to pull harder to keep the object to the planet's surface. Hope this helps! :)
