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