The correct answer is A) FIRST FIREMAN: We are the fireman Mr. Barclay (They remove their hats).
The line from “The Still Alarm” by George S. Kaufman that contains a parody of the British society is “FIRST FIREMAN: We are the fireman Mr. Barclay (They remove their hats).”
The line has a parody of the British society because it shows the calmness and the proper manner in which the character conducts himself in that moment. The background is that there is a fire in the hotel where he is with other people. The situation is riskier because the fire is reaching the place where they are. So when the Firemen gets to the scene they introduce themselves in a very proper way, removing their hats indeed, as if nothing were happening. That is a parody of the excessive formality of the British. In real life, during an emergency situation like that, everybody is rushing, trying to save their lives and the fireman act swiftly, ordering, proceeding firmly and confidently.
