Solution
The correct option is ANO2 and O3
NO2 and O3 both of these have permanent dipole moment.
O3 have similar atom but still it have dipole moment as there is unequal sharing of valence electrons O3 molecule is not symmetrical. Which results in the difference in charges. Hence, O3 has a permanent dipole moment.
