It is option 'b', since you cannot remove the building as mentioned in option 'a'. Water does reduce the temperature of both wood and paper below their ignition temperature to combust fire. Option 'c' is partially correct but also wrong since co2 does form a blanket around the flame, cutting out o2 supply, but it does this because it is heavier then o2, not light.
