White has just played Nb4-a2+, because otherwise Black would have moved into check, which is not a legal move.
Before that, Black can't have moved his King, so there was another piece on the board, which was captured by White's last move. It must have moved to a2, so it can't have been a Pawn or a Knight. A Rook or Queen would have come from the first rank - impossible (White in check). This leaves Bb1-a2 as Black's last move, which changes White's answer to Nb4xa2+.

Excellent answer.
Irresistible nitpick: Black bishop could have also captured a White piece on a2.
