(C) Let $B = A - A^T$. To check if $B$ is symmetric or skew-symmetric,we find its transpose $B^T$.$B^T = (A - A^T)^T$Using the property $(X - Y)^T = X^T - Y^T$,we get:$B^T = A^T - (A^T)^T$Since $(A^T)^T = A$,we have:$B^T = A^T - A$$B^T = -(A - A^T)$$B^T = -B$Since $B^T = -B$,the matrix $A - A^T$ is a skew-symmetric matrix.
