Correct Answer - B
`H_2O` have bent structure in which the two O-H bonds are oriented at an angle of `104.5^@` , so water have a net dipole moment whereas `BeF_2` have linear geometry, so the dipole moment of one bond is cancelled by another bond, so it have zero dipole moment.

`H_2O` has net dipole moment while `BeF_2` has zero dipole moment because
