Your answer is not correct.
To find the correct answer, let's break down the options:
A. A compound is a substance made up of two or more different kinds of atoms that are chemically bonded together. Since we are looking for a substance made up of only one kind of atom, compound is not the correct answer.
B. A homogeneous mixture is a mixture where the composition is uniform throughout, but it contains more than one kind of substance. Since we are looking for a substance made up of only one kind of atom, homogeneous mixture is not the correct answer.
C. An element is a substance made up of only one kind of atom. This is the correct answer.
D. A solution is a mixture where one substance dissolves into another and it can contain more than one kind of substance. Since we are looking for a substance made up of only one kind of atom, solution is not the correct answer.
