A)  Ionization isomerism

B)  Coordination isomerism

C)  Geometrical isomerism

D)  Linkage isomerism

Correct Answer: C

Solution :

In \[\text{ }\!\![\!\!\text{ CoC}{{\text{l}}_{\text{2}}}{{\text{(en)}}_{\text{2}}}\text{ }\!\!]\!\!\text{ }\], Coordination number of Co is 6 and this compound has octahedral geometry. As per given option, type of isomerism is geometrical isomerism.
