Solution

The correct option is A strong, weak
Graphite has carbon atoms which are covalently bonded with three other carbon atoms.
These are linked in hexagonal arrangement forming 2D sheets stacked over one another.
The covalent bonds within the layer are strong but the layers are held by weak van der Waals forces.
The weak force between the layers makes it a good lubricant but the strong bonds within the sheet makes it hard to melt.
