What layer in the sun, is the coolest?

The Photosphere is the luminous surface that delimits the Sun as a star, besides being the coldest layer produces the light that is visible from the Earth.

This surface is composed of a layer of gases that are subjected to strong pressures and its temperature is only (very cold compared to the of its hottest layer).

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
