Verified by ExpertsThe correct answer is:
A
has symmetrical tetrahedral shape which is due to 
hybridisation of the central silicon atom in its excited state configuration.
has distorted tetrahedral or sea ‐ saw geometry which arises due to 
hybridisation of central sulphur atom and due to the presence of one lone pair of electrons in one of the equatorial hybrid orbitals.
