Consider the following in context of difference in the properties of diamond and graphite and mark the incorrect statement.

In diamond there is a three dimensional network of strong covalent bonds whereas graphite layers are held by weak van der Waal’s forces

Diamond is bad conductor of electricity whereas graphite is a good conductor

Melting points of graphite is low but that of diamond is very high

Graphite can be converted into diamonds by the action of high temperature and high pressure

Explanation:

Graphite has a melting point similar to that of diamond of around 3600°C, at which point it sublimes rather than melting. In order to melt graphite, it isn't enough to loosen one sheet from another (which are connected by vanderwaal's bond). You have to break the covalent bonding throughout the whole structure.
