基本操作可以通过以下方式轻松实现enumitem的label键值方法：

\documentclass{article}

\usepackage{enumitem}

\begin{document}

\begin{enumerate}[label={Q.\arabic*}]
  \item \mbox{}
  \begin{enumerate}[label=\alph*)]
    \item
    \begin{enumerate}[label=(\roman*)]
      \item What is physics?
      
      \item Examples of branches of physics.
    \end{enumerate}
  \end{enumerate}
\end{enumerate}

\end{document}
