Solution

The correct option is B 2
According to VBT, a complex with CN=4 can have two possible types of hybridisation and hence two geometries.
$s p^{3}$ hybridisation results in a terahedral structure. $d s p^{2}$ hybridization results in square planar geometry.
Hence, option (b) is the correct answer.
