As a suggestion, I will say that the answer is: D. I seized the bell-rope; dropped it, ashamed; seized it again; dropped it once more; clutched it tremblingly once again, and pulled it so feebly that I could hardly hear the stroke myself. I say D. because the description allows you to see the pilot clumsily dropping the rope over and over again. You can also picture his embarrassment and shame due to his lack of focus and tact. That is just my opinion. If you think otherwise, you can choose otherwise. I wish you the best, on your test.
