Correct option is C
The correct answer is “ BADC”.
In this context, the speaker describes a situation where they were positioned on one side of a creek, engaging in a conversation with a lady situated on the other side. The lady noticed something near the speaker's feet and asked about it. The speaker is recounting a personal experience where they found themselves on one side of a creek, engaged in a conversation with a lady positioned on the opposite side.
Thus, the correct sentence formed will be “I was on one side of the creek and this lady was talking to me on the other side and she said what's that at your feet.”
