The 'd' orbitals of Cadmium are full filled therefore transition of electrons is not possible within 'd' orbitals so compound is colorless.

IT IS CADMIUM CARBONATE CaCo3
Calcium oxide
cadmium diiodide or cadmium (II) iodide --------- Right Answer: Cadmium iodide
Cadmium sulfide It is a compound of Cadmium (Cd) and Sulphur (S).
Cd(NO3)2 + Na2CO3 --> 2 NaNO3 + CdCO3 Cadmium Nitrate + Sodium Carbonate --> Sodium Nitrate + Cadmium Carbonate.
