根据矩阵的运算规律，$(\boldsymbol{A} + \boldsymbol{B})^{\mathrm{T}}$ $=$ $?$选项
[A]. $(\boldsymbol{A} + \boldsymbol{B})^{\mathrm{T}}$ $=$ $\boldsymbol{A}^{\mathrm{T}}$ $+$ $\boldsymbol{B}^{\mathrm{T}}$[B]. $(\boldsymbol{A} + \boldsymbol{B})^{\mathrm{T}}$ $=$ $\boldsymbol{A}^{\mathrm{T}}$ $-$ $\boldsymbol{B}^{\mathrm{T}}$
[C]. $(\boldsymbol{A} + \boldsymbol{B})^{\mathrm{T}}$ $=$ $(\boldsymbol{A} \boldsymbol{B})^{\mathrm{T}}$
[D]. $(\boldsymbol{A} + \boldsymbol{B})^{\mathrm{T}}$ $=$ $\boldsymbol{A}$ $+$ $\boldsymbol{B}$
$(\boldsymbol{A} + \boldsymbol{B})^{\mathrm{\textcolor{orange}{T}}}$ $=$ $\boldsymbol{A}^{\mathrm{\textcolor{orange}{T}}}$ $+$ $\boldsymbol{B}^{\mathrm{\textcolor{orange}{T}}}$
