Answer

Brief Explanations:

An element consists of only one type of atom. A heterogeneous mixture has visibly different components. A homogeneous mixture has uniform composition but is a physical combination. A compound is a pure - substance made up of two or more different types of atoms chemically combined in a fixed ratio. Since substance A has sodium, oxygen, and hydrogen atoms in a fixed ratio of 1:1:1, it is a compound.

Answer:

A. a compound
