Answer:
The correct answer is option B) Mixture.
Step-by-step explanation:
When two or more substances are mixed but they do not lose their properties then we are in the presence of a mixture.
An example of this is the air we breathe, where many gases are mixed but not chemically combined.
That is why a mixture differs from a chemical compound, where substances can change their chemical composition when mixed.
Given this information we can say that the correct answer is option B.
