Air is the right answer.
Further explanation
Compound
It can be defined as a substance that outcomes from the combining of at least two distinctive components so that the atoms of the various components are held together by chemical bonds that are hard to break.
Examples of compound
Diamond, water and graphite are common examples.
Structure of diamond
It is composed of a large lattice structure with solid covalent bonds between carbon particles. Every carbon atom has 4 bonds.
Structure of graphite
Graphite has a covalent structure in which every carbon particle is joined to three other carbon atoms by covalent bonds. the carbon particles make layers with hexagonal atoms.
Structure of water
It is a molecule with the sub-atomic equation H2O, comprising of two light hydrogen atoms joined to an oxygen molecule.
Mixture
It contains at least two substances that are not chemically bonded.
Example of mixture
Sand, Air and salad.
Air
Air is a mixture of different gasses. like oxygen, nitrogen and carbon dioxide, etc.
Composition of air
