    令\(F_n = \{次数小于n的多项式全体\}\).\(T:F_3 \to F_3\)定义为\(T(f) = f'\)是微分映射.在基\(\{1,x,x^2\}\)下,\(T\)对应的矩阵为____.
    A: \(\begin{pmatrix}0&0&0\\1&0&0\\0&2&0\end{pmatrix}\)
    B: \(\begin{pmatrix}0&0&0\\1&0&0\\0&1&0\end{pmatrix}\)
    C: \(\begin{pmatrix}0&1&0\\0&0&1\\0&0&0\end{pmatrix}\)
    D: \(\begin{pmatrix}0&1&0\\0&0&2\\0&0&0\end{pmatrix}\)
