Dear all,
I have some questions about conformung elements. I include a wonderful diagarm below

. My elements are the grey ones (so enemies are white

).
I want to move group 1-4 into contact with group A-D, but two elements are fighting partially in front os A. A's TZ is not obstructed, so 1 is pinned by it, but 1 cannot conform to A's front. What's the correct option?
1. Group A-D is lined up to fight against 1-4 as per bullet three of front edge contact.
2. Element 1 is moved behind element 2 and then group 1-4 is lined up against A-D (2 vs B, 3 vs C and 4 vs D) as per point c) of extra move to line up
Thank you very much.
