Why tetrahedral complex do not exhibit geometrical isomerism?

Tetrahedral complex cannot show geometrical isomerism .

Tetrahedral complex cannot show geometrical isomerism .

Which of the following statements is true A) Ma_3b_3 type of complex exhibits fac-mer isomerism B) Tetrahedral complexes do not exhibit optical isomerism C) [Co(en)_3]^(3+) shows optical isomerism D) [Pt(en)_2Cl_2] does not exhibit optical isomerism

Assertion :Tetrahedreal complex do not show geometrical isomerism Reason: The relative position of the ligand attached to the central metal atom is same with respect to each other.

Assertion : The IUPAC name of the complex compound [Co(H_2O)_4Cl_2]Cl. 2H_2O is tetra aquadichlorocobalt (III) chloride. Reason: Tetrahedral complexes exhibit geometrical isomerism.
