You should edit the post then. Right now it says “you prevent them both from getting malaria”, which is the exact opposite of what you said just now. In this case I agree that the GiveWell view is indifferent between B, C, and D. Births that may result from or be prevented by AMF (which I would argue is pretty negligible) simply aren’t considered in the cost-effectiveness analysis. There’s nothing contradictory about this.
