If \( \mathrm{A}_{1}, \mathrm{~A}_{2}, \mathrm{~A}_{3}, \ldots, \mathrm{A}_{2 n-1} \) are \( n \) skew-symmetric
\( \mathrm{P} \) matrices of same order, then

W \( \mathrm{B}=\sum_{r=1}^{n}(2 r-1)\left(A_{2 r-1}\right)^{2 r-1} \) will be
(A) symmetric
(B) skew-symmetric
(C) neither symmetric nor skew-symmetric
(D) data not adequate
