Monodentate ligands are those that can bind to a metal center through only one donor atom. In option (b) and (d), both ligands (chloride and water) can bind to a metal center through only one donor atom. Therefore, the correct option is B. Option (a) and (c) have bidentate ligands (diethylenetriamine and ethylenediamine) that can bind to a metal center through two donor atoms.
