Answer: Apatite
Explanation: According to the Mohr's hardness scale, fluorite has a hardness of 4, whereas amphibole (which belongs to the hornblende field) has a hardness of about 5-6. And the hardness of apatite is 5.
So by comparing their hardness, we can determine that Apatite can easily scratch the mineral fluorite because it has higher hardness than fluorite, but apatite will not be able to scratch amphibole because apatite has a lower hardness compared to amphibole.
