Correct Option - 4

Detailed Solution:

$[C o {(N H_{3})}_{3} {(N O_{2})}_{3}]$ shows Facial and Meridional geometrical isomerism.

$[C o C l_{2} {(e n)}_{2}]$ shows cis and trans geometrical isomerism.

${[C o {(N H_{3})}_{4} C l_{2}]}^{+}$ shows cis and trans geometrical isomerism.

${[C o {(C N)}_{5} (N C)]}^{3 -}$ can not show geometrical isomerism.
