Solution
The correct option is C Carbon
Diamond, graphite, the element silicon and silicon dioxide are examples of covalent substances with very high melting points. These substances don't exist as molecules. Instead they have giant network structures - something like the ionic lattices, except that the bonds are all covalent. So the carbon shows the covalent network solids.
