B & A are going to be good, but IMHO not as good as India. I see India at the #1 spot around 2050. More people - as a billion. More education, and people moving back from the US to share their experience. Democracy (improving), and a wariness of how leftist reforms seriously damaged their country in the past. If they can fix the bureaucracy, it's going to be quite hot. (and BTW I'm not indian, this is not some personal bias - I just see a lot of potential)
