micheus, definitely the second (lowermost) option! although it seems to me the faces alongside the red (then yellow) line must be co-planar, or else we wouldn't have a solid group (like in the top example).
having co-planar faves at this point of the discussion and not being 100% certain these actually are co-planar or not is confusing to me.
considering this, none of the above options is correct
