Which complexes show geometrical isomerism ?

In which of the following pairs both the complexes show geometrical isomerism?

Assertion : Geometrical isomerism is also called cis-trans isomerism . Reason : Tetrahedral complexes show geometrical isomerism .

Which of the following octahedral complexes do not show geometrical isomerism ?

Read the paragraph carefully and answer the questions given below it, Stereo//space isomerism in coordination compounds Gcometrical isomerism: Exhibited by square planer and octahedral complexes (not by tetrahedral complexes because relative positions are similar). If opposite positions have similar groups, it is trans, otherwise it is cis, Optical isomerism: Shown when mirror image is non-superimposable. Cis-isomer shows but trans isomer does not QWhich of the following types of square planar complexes can show geometrical isomerism (where M = metal and a, b = achiral ligands)
