Dipole moment is a vector quantity and by convention it is depicted by a small arrow with tail on the negative centre and head pointing towards the positive centre. But in chemistry presence of dipole moment is represented by the crossed arrow put on Lewis structure of the molecule. The cross is on positive end and arrow head is on negative end. So, statement I is incorrect. The crossed arrow of the dipole moment symbolises the direction of the shift of electron density in the molecules. So, statement II is correct. Hence the correct option is B
