This formation is 3-2-3W-2. It is a very attacking formation, with 5 players as AMs or STs. To utilise, in my opinion, tactics should be at least attacking or hard attacking.

Both A) and B) won’t work well. Opponent playing most formations with AML/ST/AMR will easily breach both the midfield and side-back areas, as there are no proper DL, DR, ML or MR. (That MR is positioned next to MC margin acting as a MC [presumably superior to other MCs available], and would not provide sufficient cover for MR or DR area. DL and DR are both practically DC)

C) Attacking or Hard Attacking. Mixed or flanks both would do, mainly depending on opponent having DMC or not. Would pull the AMC to the region next to MC area and without arrow if there is DMC, and also use flanks, as that AMC will act as a passer-in-between for attacks when switching flanks and not too affected by the DMC.

Maybe that MR should be better to be without the upper arrow, or else that area could be very vulnerable to counter-attacks.

Just my own opinion there.
