b) the highest temperature of the proplyd
c) the local temperature of the proplyd
d) the distance of Jupiter

Explanation / Answer

1) c) the planet has no cloud cover

Albedo (or reflection coefficient) is the ratio of the reflected radiation to that of the incident radiation. Thus, for a planet with cloud/higher gaseous content would have a higher albedo since these entities reflect most of the radiation incident upon them. Lower albedo is a sign of lower or no cloud cover.

2) c) the mantle can easily be absorbed into the Earth's core

The rest of the option are the result of the mantle's plastic flow which occurs due to the temperature difference between the top and the bottom of the mantle.

3) a) core temperature

this is because the higher the core temperature higher is the fusion (by the p-p chain and/or CNO cycle) reaction. This would indicate whether the environment is solid or gas.
