`A` is a matrix of `3xx3` and `a_(ij)` is its elements of `i^(th)` row and `j^(th)` column. If `a_(ij)+a_(jk)+a_(ki)=0` holds for all `1 le i, j, kle 3` thenA. `A` is a non singular matrixB. `A` is a singular matrixC. `sum_(1 let i, j le 3)a_(ij)` is equal to zeroD. `A` is a symmetric matrix |

Answer» Correct Answer - B::C Put `i=j=k` `a_(ij)=0` and put `k=iimpliesa_(ij)=-a_(ji)` So, matrix is skew symmetric of odd order. |
