Solution
The correct option is DOSF2 The species having a pyramidal shape according to VSEPR theory is OSF2. The central S atom has 3 bonding domains ( one S=O double bond and two S−F single bonds) and one lone pair of electrons.
The electron pair geometry is tetrahedral and molecular geometry is pyramidal. This is similar to the ammonia molecule.
