Which statement about the electric dipole moment is true?

u=qd

a) A molecule is a strong dipole if the net charge separation occurs over a short distsnce within the molecule
b) the unit of u is C/m
c)A dipole exerts a larger force on a point charge than on another dipole at the same distance.
d)for strong dipole molecules, u is typically a value on the order of 1*10^-30 C*m while the elementary charge is 1.6*10^-19C. Thus the charge separated in strong dipole molecules in many orders of magnitude less than an elementary charge
e)The dipole moment can be zero even if neither q or d is zero.

I think that e is correct, I just wanted to check..
