Pure substances and matter are two of many different types of mixtures.

Answer 1

The answer you are looking for is the second option, "Matter can be divided into two groups: pure substances and mixtures."

A pure substance can describe a pure element or chemically bonded elements. A pure substance cannot be broken down into further substances. An example of these would be Fe (iron) or O2 (oxygen).

A mixture is a structure made from physically combining different non-bonded substances. An example of a mixture is blood.

Both pure substances and mixtures are types of matter.
