Vedclass · Answer

(C) molecule is polar if its net dipole moment is non-zero $(\mu 
eq 0)$.
$CO_2$ (linear),$BF_3$ (trigonal planar),$CS_2$ (linear),and $SO_3$ (trigonal planar) are non-polar due to their symmetric shapes.
$SO_2$ and $SCl_2$ have bent (angular) geometries with lone pairs on the central atom,resulting in a net dipole moment.
Therefore,the pair of polar species is $SO_2$ and $SCl_2$.
