- ATo prevent evaporation
- BTo prevent from moisture
- ✓To prevent it from oxidation to form phosgene
- DTo prevent its reaction with glass
✓

Correct option: C.
To prevent it from oxidation to form phosgene
c
Chloroform is slowly oxidised by air in the presence of light to an extremely poisonous gas phosgene. Thus it is stored in closed dark coloured bottles completely filled so that air is kept out.
