Question diagram
A

Geometrical isomerism

B

Linkage isomerism

C

Optical isomerism

D

Coordination isomerism

Correct Answer

Option A

Detailed Explanation

In the complex [Co(NH3)3(NO2)3], geometrical isomerism arises when the NO2 ligands occupy different positions around the central metal ion, forming either facial or meridional isomers.
