Which of the following statement(a) is/are correct?

Between the layers of graphite van der Waals' forces are present. Because Van der Waals forces are the weak interactions that exist between the covalent bonds in graphite. 

Heat and electricity are well-conducted through graphite. Because a free electron that transmits electricity is present, it has a high conductivity. Thus, Van der Waal forces—weak attractive forces—are present in graphite.
