Which statement is true about inorganic compounds?

They are not made of atoms.
They contain carbon.
They are not made from living things.
They are all elements.

They are all elements

Explanation:

1) INORGANIC COMPOUNDS ARE COMPOUNDS THAT ARE NOT MADE UP OF CARBON AND HYDROGEN.

2) They are also not made from living organisms, it's rather organic compounds that are made from living things
