Totally agree on avoiding Lambda due to that long processing time. B stands out because auto-scaling with queue depth keeps it efficient and handles spikes smoothly. Definitely B.

Makes sense to avoid Lambda here since the fraud check takes so long and Lambda has timeout limits. B is solid because it scales with queue depth, handling the burst well.
