What defines a mixture?

A) A mixture contains different substances that are chemically combined.

B) A mixture contains different substances that are not chemically combined and can be broken down into its basic substances through physical means.

C) A mixture is created through a chemical reaction.

B is your best answer because a mixture is when two or more things combine but not chemically. Take soup for example you take out all the pieces because they didn't combine together and just become 1 thing they still have parts. You can still take the noodles, you take the fish or meat out still, you take the broth away to.
