In February 2006, the X and Y sections of a certain expressway entered the bidding stage, and four units of A, B, C, and D were bidding. Xiao Wang believed: It is not the A family won the bid, or the B family won the bid. Xiao Li believes : Both A and C can win the bid. Xiao Zhou said: It cannot be said that if D wins the bid, then C wins the bid. Xiao Ma thinks: Dcannot win the bid.
The correct answer that will not win the bid is B,D if only one of the four people is wrong.
