Answer:

Correct Answer: 3. (d)

Solution:

  1. The maximum possible denticities of given ligand towards a common transition and inner transition metal ion, are $6$ and $8$ respectively.

The given ligand act as hexadentate ligand in transition metal ion because the common oxidation state shown by them is $+3$ . Whereas in case of inner transition metal ion, its denticity is $8$ because their common oxidation state is $+4$ .
