Answer:
I believe the best option is letter D. She alluded to her husband's affair by the use of the word spree.
Explanation:
The interaction we are studying here takes place toward the end of the novel "The Great Gatsby". Tom, Daisy's husband, knows that she's been having an affair with Gatsby. However, instead of letting her go, he chooses to claim that he loves her. He says he sometimes has affairs, but his mind is always faithful to her:
“She does, though. The trouble is that sometimes she gets foolish ideas in her head and doesn’t know what she’s doing.” He nodded sagely. “And what’s more, I love Daisy too. Once in a while I go off on a spree and make a fool of myself, but I always come back, and in my heart I love her all the time.”
As we can see, when Tom says he goes "off on a spree", he is alluding to the times he has affairs with other women. Daisy's response, even though addressing Nick and not Tom directly, uses the same expression is a more sarcastic way. She is probably angered by his using a euphemism to refer to his unfaithfulness:
"...I'm surprised that they didn't treat you to the story of that little spree."
