#sp^2#

Explanation:

The electron pairs arrangement around sulfur is trigonal planar with a bond angle of around #120^@#.

For sulfur to achieve this geometry the orbitals #s# and #p# will mix to form three new hybrid orbitals called #sp^2# leaving a non hybridized orbital #p# for the lone pairs on sulfur.

For the oxygen atoms, we should consider the hybrid form of #SO_2#:

In the hybrid form the electron pairs arrangement around oxygen is also trigonal planar with a bond angle of around #120^@#.

For oxygen to achieve this geometry the orbitals #s# and #p# will mix to form three new hybrid orbitals called #sp^2# leaving a non hybridized orbital #p# for one of the two lone pairs and the second will be in a #sp^2# hybrid orbital.
