9C.7 Which of the following isomers of diaminobenzene can form chelating complexes? Explain your reasoning.

I'm more confused about the reasoning aspect of this. Thank you!

A complex between a metal and a polydentate ligand is a chelating complex. For this situation, there are 2 binding sites on each isomer. The nitrogens have to be close enough to complex to the same metal atom, so it would have to be (b).

Only b can form a chelating compound because only there are the NH2 groups close enough to bind to the same atom
