Question 1070705
<pre>
I've only found one way to make such a circle, other
than to rotate it and/or reverse it:

             1
         4      3
       2          6
      5            8
       7          11
        10       9
            12

It has 6 and 8 as neighbors, but none of the others.

So the correct choice, if it can be one of those, it 
can only be (D)
