What you're looking for in here is the hardness: a material can scratch another material if it's harder than it.

So the desired material cannot be harder than amphibole, which has a hardness of 6.

But it has to be harder than fluorite, which has a hardness of 4.

So we're looking for a hardness of between 4 and 6 and from the table we see it's magnesite (we'll need a hard magesite) - this is the correct answer!
