Indicate the complex ion which shows geometrical isomerism.

$\lbrack Cr(H_{2}O)_{4}Cl_{2}\rbrack^{+}$

$\lbrack Pt(NH_{3})_{3}Cl\rbrack$

$\lbrack Co(NH_{3})_{6}\rbrack^{3 +}$

$\lbrack Co(CN)_{5}(NC)\rbrack^{3 -}$

Answer

$\lbrack Cr(H_{2}O)_{4}Cl_{2}\rbrack^{+}$

Explanation

Complexes of type $MA_{4}B_{2}$ shows geometrical isomerism. Thus $\lbrack Cr(H_{2}O)_{4}Cl_{2}\rbrack^{+}$ shows geometrical isomerism.
