The sentence that you can insert in the blank is D) Waiting for Godot was in danger of closing the first week of its run and of becoming nothing more than a footnote in the annals of the English stage.
This answer is showing us a contrast of ideas an in the next paragraph we have the contrast connector "HOwever" which makes the story have a perfect flow with that sentence.
The other options are not correct because they don't cover that contrast element as option D does.
