since in skew symmetric matrices, all the diagonal entries should be zero.
and trace = sum of all the diagonal entries
thus trace = 0 in case of skew symmetric matrices
thus option D (None of these ) is right answer

All principal diagonal elements of a skew symmetric matrix are zero thus trace ie sum of all diagonal elements of a matrix is zero
