First of all C isnt needed here nor will he do anything.
The location will restrict deidora, bee and oro. Diedora cannot use c4 or c0 in the location but also it will affect his team-mates although i doubt sasori, this is in relation to c4. A is automatically immune to c4 due to his raiton armour therefore he needs no info for this. Bee is also a raiton user, but if deidora was to use c4 he would die, but the location wouldnt allow him to use c4.
Bee is restricted because he cannot go full tailed beast mode and use tbb. He can however go to v2 state and in that state none of sasori's weapons will penetrate him therefore he can easily take out sasori. I dont even think that iron san will help him. Similarly A is also a bad match up for sasori because A is also very durable but also i cannot see any of sasori's weapons landing due to his reflex and speed feat.
Either A or B will defeat any of them then in a 1 vs 1 fight. We dont know how good sasori's and deidora's team chemistry is, but A and B have a lot experience fighting together.
Anyway;
Bee > oro and sasori
A > Deidora
Bee in v2 can defeat both oro and sasori or hold them enough for A to fodderize deidora (who struggled with sasuke's speed) and help B finish sasori and oro
