Depends on SA BD series. SA has 6 games to go, 2 in BD and 4 at home (2 pak and 2 against SL). If they win all six, India needs to win 2 against NZ and have 2-2 or better against Australia. In that scenario SA and India qualify
Optimistic Case: BD beats SA 1-0, India can qualify with 2-1 against NZ and 1-4 against Australia
