Let \( A \) and \( B \) are square matrices of same order such that \( |A|=|B|=1 \) and \( A(\operatorname{adj} A+\operatorname{adj} B)=B \). The value of \( |A+B| \) is (A) \( -1 \) (B) 1 (C) 0 (D) 2 2. If \( B B^{\prime}=I \), then \( A B^{-1} \) is (A) \( B^{-1} A \) (B) \( A^{-1} B \) (C) \( B A^{-1} \) (D) \( B^{-1} A^{-1} \)
