Actually it’s C.ALL planets have a atmosphere but it’s toxic. We have a BIOSPHERE that’s what makes things LIVING.

The correct answer is option C, hydrosphere and biosphere

Explanation:

It is the planet earth that consists of hydrosphere (water ) and biosphere (living things) that are distinctive of other planets. Most of the planets have  atmosphere but they are not of the same quality as that of planet earth that could support life. Also some planets have frozen water (cryosphere) beneath their surface crust such as moon , venus etc. and lithosphere is present in all the planets with distinctive features and characteristics from each other.
