Options

A. The colour of the transition metal compounds having incompletely filled d- orbitals in the metal ions is due to `d-d` transition
B. Intense colours occur due to charge transfer i.e, transfer of electrons from the ligand to the metal
C. The colours of `AgBr, Ag_(2)CO_(3), Ag_(3)PO_(4), Ag_(2)O, Cu_(2)O` etc is due to polarizing power of transition metal ion and polarisability of anion
D. The colour of a particular transition metal ion is independent on the nature of ligand

Answer
