St. George Defence/Three Pawns Attack edit

In this position, the pawn cannot take the knight as 6. Qxb7 would be deadly. Two options are offered to black according to the former author, but only one is alright:

5...Ra7 protects the bishop, allowing the pawn to take the knight, but hangs the pawn. Therefore, 5...Ra7 is out.
5...Nc6 is a good move, defending the b pawn and attacking the now undefended d pawn.
