C is the correct answer.

Explanation:
A and b don’t show anything that is different between the rocks so they are both cancelled. With D, if a block has a greater volume that has nothing to do with the substances. This shows that C is the best answer because if one block conducts electricity, that means it is composed of something different (for example metal).

Answer: I think the answer would be (D) because mass and volume are kinda different and If one has a different volume then it would have a different mass right?

weeeeeb [17]

Answer:

Gravitational force

Explanation:

Gravitational force is the force that attracts an object down to the earth. It’s also the reason why we don’t float on this planet. This force is also why anything that isn’t thrown up must come down.

In space and other planets with little or no gravitational force ,organisms float over there which makes its inhabitation by organisms very difficult.
