As the moon moves out of Earth's shadow, the moon's surface is warmed by sunlight. Which type of heat transfer is this?
A conduction
B convection
C radiation

Explanation:  

Heat energy reaches other planets and satellites of the solar system through the process called radiation.

In this process , the heat energy travels in the form of electromagnetic waves which do not require any material medium . It is so because it is a non mechanical wave . Hence heat energy reaches earth or moon even when there is no material medium between sun and the moon . Other mode of transfer of heat requires medium like solid or liquid or gas to travel from one point to another .

whichever one it is, it's definitely not one that you included on the list you provided.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
