Ah, Dan beat me to it, and has done a better job. Since I did draw it out, I am going to show mine as well.
I am going to choose a different explanation as well. Based upon the drawings, I thought B, D, and the poster's structure were correct, except the poster ignored the bond in front issue. If other orientations were among the answers, then I too would have agreed with Dan. However, this looked like a rather plain and simple change (except for the error). Furthermore, I didn't know whether the structural error was the poster's error or one created in the problem. So I tried to give a hint that I thought the poster could analyze to get the correct answer.
