Let E be the electric field and V be the electric potential at a point

a if E is not 0 V can not be 0

b if E=0 V must be 0

c if V=0 E must be 0

d none of these

Electric potential is a scalar quantity, that is only the strength of charge at particular point.
But Electric field is a vector quantity that is associated with direction as well as magntude..
If Vis zero, mean no charge, then no sense of ELECTRIC FIELD.
