Understand the definitions of the given terms: An element is a pure substance consisting of only one type of atom.
A compound is a pure substance made of two or more different atoms chemically bonded together in a fixed ratio.
A heterogeneous mixture contains different substances that are not evenly distributed, so you can often see different parts.
A solution is a homogeneous mixture where two or more substances are evenly dispersed at the molecular level, appearing uniform throughout.
Since the problem states the mixture is evenly dispersed at the molecular level, it fits the definition of a solution.
