consider the following code:
\documentclass{scrartcl}
\usepackage[ngerman]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{graphicx}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{enumerate}
\theoremstyle{plain}
\newtheorem{thm}{Theorem}
\theoremstyle{definition}
\newtheorem{rmk}[thm]{Remark}
\begin{document}
\begin{thm}
Normal theorem.
\end{thm}
\begin{proof}
Normal proof.
\end{proof}
%%%%%%%%%%%%%%%%%%%%%%
\begin{rmk}
\begin{enumerate}[(a)]
\item Some remark.
\begin{proof}
Proof for that remark. %!!!
\end{proof}
\item Other information.
\end{enumerate}
\end{rmk}
\end{document}
