如何拆分长表单元格并根据图像宽度调整宽度

Question

我正在尝试绘制一个包含图像的长答案表。

我的努力是多列并将单元格拆分成小表格。我无法根据图像的宽度调整小表格的宽度。我的 MWE，请帮帮我！

\documentclass[12pt,a4paper,twoside]{report}
\usepackage[utf8]{vietnam}
\usepackage[left=2cm,right=1.5cm,top=2cm,bottom=2cm, a4paper]{geometry}  
\usepackage{longtable,tikz,multirow}
\begin{document}
\begin{longtable}{|c|c|p{0.7\linewidth}|p{0.1\linewidth}|}
\hline
\textbf{Ex} & \textbf{Ideas} & \textbf{Answer} & \textbf{Mark}\\
\hline
\multirow{3}{*}{\textbf{1}}& a) & Answer one & \textbf{1,0} \\
\cline{2-4}
& b) &
\multicolumn{2}{|l|}{
    \begin{tabular}{@{}p{0.3\linewidth}l}
    \parbox{0.4\linewidth}{\begin{tikzpicture}
    \draw (0,0) circle (2.5);
    \end{tikzpicture}}&
    \begin{tabular}{|p{0.4\linewidth}|p{0.1\linewidth}@{}|}
    Answer 2 &0.25\\
    \hline
    Answer 3 &0.25\\
    \hline
    Answer 4 &0.25\\
    \hline
    Answer 5 &0.25\\
    \hline\\
    \end{tabular}
    \end{tabular}
}\\
\hline
 & c)& Answer 6 & 1.0\\
\hline
\end{longtable}
\end{document}

先感谢您！
