Q. Which compound is zero valent metal complex?
A) $\lbrack Ni(CO\left. \ \ \right)_{4}\rbrack$
B) $K_{3}\lbrack Fe(CN)_{6}\rbrack$
C) $\lbrack Pt\left( NH_{3} \right)_{2}Cl_{2}\rbrack$
D) [Cu$\left( NH_{3} \right)_{4}SO_{4}\rbrack$
Explanation
(a)
CO ligand has zero oxidation state, that is why [Ni$(CO)_{4}\rbrack$ is a zero valent metal complex
