    Correct Answer: B

    Solution :

    The complexes, in which, the metal and ligand form a bond that involves the \[\pi -\]electrons of the ligand  are know as \[\pi -\]complexes e.g. Ferrocene \[Fe\]\[{{({{\eta }^{5}}-{{C}_{5}}{{H}_{5}})}_{2}},\] zeise?s salt  \[K[PtC{{l}_{3}}({{\eta }^{2}}-{{C}_{2}}{{H}_{4}})]\].
