Solution

If the complex ${\text{MA}}_{\text{2}}{\text{B}}_{\text{2}} \text{is} {\text{ sp}}^{3}$ hybridised then the shape of this complex is tetrahedral this structure is optically inactive due to the presence of plane of symmetry

Optical isomers = 0 (b) If the complex ${ \text{MA}}_{\text{2}} {\text{B}}_{\text{2}} \text{is} { \text{dsp}}^{2}$ hybridised then the shape of this complex is square planar.

JEE Main 2020 Chemistry, Coordination Compounds — solution figure 2

Both isomers are optically inactive due to the presence of plane of symmetry. Optical isomers $=0$
