Answer: C
In this excerpt, Granny remembers her past. Specifically, she is trying to remember how, so many years ago, she was stood up at the altar. As she remembers, she thinks of a dark cloud of smoke. The dark cloud rose and covered all her memories. She claims that it rose over a field where everything was planted in orderly rows. The orderly field represents Granny's dreams, while the cloud of smoke shows how her dreams were destroyed when she was stood up at the altar.
