Element: each of more than one hundred substances that cannot be chemically interconverted or broken down into simpler substances and are primary constituents of matter. Each element is distinguished by its atomic number, i.e. the number of protons in the nuclei of its atoms, or a part or aspect of something abstract, especially one that is essential or characteristic.
Compound: a thing that is composed of two or more separate elements; a mixture, or made up or consisting of two or more existing parts or elements.
Homogeneous mixture: A mixture where the composition is constant through out. There is a bigger definition if you look up Homogeneous mixture definition
Heterogeneous mixture: A heterogeneous mixture is often composed of different solids, or of matter existing in two or more different phases. Phases are states of matter; there are three well-known phases: gases, liquids, and solids.
Solution, in chemistry, a homogenous mixture of two or more substances in relative amounts that can be varied continuously up to what is called the limit of solubility. The term solution is commonly applied to the liquid state of matter, but solutions of gases and solids are possible.
Some of these answers are from a online dictionary. Others were Ctrl + C and V from other websites like(sciencetrends.com/heterogeneous-mixture-definition/) and (www.britannica.com/science/solution-chemistry#:~:text=…)
So probably Homogeneous mixture
