Answer: The correct answer is D) One substance can be separated from another through physical means.
Mixture is a combination of two or more substances that are combined or mixed physically in a way that they do not loose their identity.
This means that mixture does not undergo any chemical change and it can be separated through physical means (like filtration). It can be of solid, liquid, or gaseous molecules.
Mixture can be primarily divided into homogenous ( having uniform composition that is every sample will have same property) and heterogenous mixture ( non uniform composition that is not every sample will have same property).
Thus, option D) is a property of every mixture.
