How it is considered as a element ?

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

The correct answer is option D because diamond is an allotrope of carbon which means it has all the properties of carbon because carbon is an element itself.

Diamond is a hardest substance, diamond has a all properties of carbon.

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

Probably Diamond is not the hardest substance on earth.

Diamond is allotroph of carbon.

ITS NOT AN ELEMENT.

DIAMOND IS A HARDEST SUBSTANCE.

dimond is a form of carbon

Diamond is made of pure carbon, with carbon atoms arranged in a cubic structure and bonded to their neighbors in a very compact way.

So, diamond is made of an element but it is not an element. It is not a compound either, because, by definition, a compound is made up of two or more elements.

I would say diamond is crystalline form of carbon, that is, it is composed merely of carbon atoms in a highly structured arrangement.
It is carbon, like charcoal, but its more expensive due to its good properties and the fantastic marketing to the gullible public.
