The correct answer is:

CHECK THE SOLUTION.

(a, b, d)

The colour of the transition metal ions / compounds is attributed to d-d transition of electrons e.g. in [Cu(NH3)4]2+.

Charge transfer spectrum e.g. in MnO4– (no d electrons present).

The colour change is not because of change in the geometry of the molecules.

Yellow colour of the AgI is due to the polarisation of I– by Ag+.
