Solution

The correct option is D All of these
Strongly heating Potassium dichromate, Potassium Permanganate or Potassium Chlorate gives oxygen gas.

Heating above 400C, the following reactions takes place
4K2Cr2O74K2Cr2O4+2Cr2O3+3O2
2KMnO4K2MnO4+MnO2+O2
2KClO32KCl+3O2
Thus all of them release oxygen gas on heating above 400C. These reactions can be used in the preparation of oxygen gas in laboratory.
