What so we call the kind of salt from a salt mine?

salt mine is a mine from which salt is extracted. The mined salt is usually in the form of halite (commonly known as rock salt), and extracted from evaporite formations.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
