ANSWER: d5 x e6 (the white pawn on d5 captures the black e5 pawn on square e6 "en passant").
EXPLANATION: Mate in one is possible only if black's previous move was e7 to e5. White can then capture the black pawn "en passant" on e6. The discovered check by the white bishop on b2 will checkmate the black king.
