D; You could make some argument for A only but for this the best answer would be D
Ionic bonds generally have higher melting points due to stronger electrostatic interactions.
At the molecular level, temperature is related to the random<span> motions of the particles (</span>atoms<span> and molecules) in </span>matter<span>. Because there are different types of </span>motion, the particles' kinetic energy (energy of motion) can take different forms, and each form contributes to the total kinetic energy of the particles.<span>

Radiation: Radiation is the final form of movement of heat energy<span>. The </span>sun's<span> light and </span>heat<span> cannot </span>reach<span> us by conduction or convection because space is almost completely empty. There is nothing to </span>transfer<span> the </span>energy<span> from the </span>sun<span> to the </span>earth<span>. The </span>sun's<span> rays travel in straight lines called </span>heat<span> rays. I hope this helps you out tunzzzzz
