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!

If the object is round and travels in an orbit around Neptune with other space objects, then this object is a moon, not a dwarf planet.
<h3>What is a natural satellite?</h3>
A natural satellite is a celestial body that moves around (orbit) a planet such as occurs with the Moon and the Earth planet.
In order to discover the nature of a celestial body scientists need to observe the orbit and the movement of these objects in space.
In conclusion, if the object is round and travels in an orbit around Neptune with other space objects, then this object is a moon, not a dwarf planet.
