Diamond had a Mohs scale measurement of 10..
But there are some elements(not on earth i think so) which has greater that 10 strength, like carbon fullerenes e.t.c...

Diamond is a form of Carbon. So, it is simply Carbon in disguise.

Yes, by definition it is wrong that Diamond is an element but it is a form of carbon where one carbon atom bonded with other four carbon atoms and form tetrahedron shape. Due to this diamond is hardest substance.

Diamond has all the properties of carbon thats why it is an element.

Ruby, topaz, emerald and sapphire are the name of corals and pearls where as diamond is the allotropic form of carbon which is obviously a metal. Diamond is a example of covalent crystal. Covalent crystals are present only in metals. Hence diamond is also a metal.

Diamond is made up of pure carbon so it is a element option (D) is correct.

Diamond's chemical formula is "C" and it gives CO2 on complete combustion. Hence it is a form of carbon (preferably allotrope of carbon).
Therefore we can conclude that diamond is an element.

Diamond is allotrop of carbon not an element.

Diamond is an allotrope of carbon but carbon is itself an element hence diamond must be an element.
Ruby, sapphire and emerald are gemstones or minerals but diamond is not a mineral.
Diamond is formed by cutting carbon at very very small angles to make it shine.
That's why its expensive.
