As in MA 2 B 2 tetrahedral structure which is sp 3 hybridised, the central metal is not chiral hence it does not show optical isomers. In the case of square planar that is dsp 2 hybridised, two geometrical isomers will form but not optical isomers. Hence, option is 0 0.

Q. The number of possible optical isomers for the complexes $M A_{2} B_{2}$ with $s p^{3}$ and $d s p^{2}$ hybridized metal atom, respectively, is :

As in $M A_{2} B_{2}$ tetrahedral structure which is sp $^{3}$ hybridised, the central metal is not chiral hence it does not show optical isomers.
In the case of square planar that is $d s p^{2}$ hybridised, two geometrical isomers will form but not optical isomers.
Hence, option is $0&0$ .
