Which excerpt from The Great Gatsby is the best example of foreshadowing?

A. "he stretched out his arms toward the dark water in a curious way, and, far as I was from him, I could have sworn he was trembling. Involuntarily I glanced seaward—and distinguished nothing except a single green light, minute and far away, that might have been the end of a dock. When I looked once more for Gatsby he had vanished, and I was alone again in the unquiet darkness."

B. "Of course I knew what they were referring to, but I wasn't even vaguely engaged. The fact that gossip had published the banns was one of the reasons I had come East. You can't stop going with an old friend on account of rumors, and on the other hand I had no intention of being rumored into marriage."

C. "I said lightly that I had heard nothing at all, and a few minutes later I got up to go home. They came to the door with me and stood side by side in a cheerful square of light. As I started my motor Daisy peremptorily called 'Wait!'"

D. "'Her family is one aunt about a thousand years old. Besides, Nick's going to look after her, aren't you, Nick? She's going to spend lots of week-ends out here this summer. I think the home influence will be very good for her.'"
