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.
