Step 1: Note the folding pattern of the paper. The paper is folded symmetrically into a diamond shape, and the text “OPEN HEART†is printed on the visible face.
\bigskip
Step 2: When the paper is unfolded and viewed from the \emph{other side}:
\begin{itemize}
\item The text undergoes a mirror reversal due to flipping,
\item Portions of the text appear in reversed orientation,
\item Relative spacing and alignment remain consistent with the folds.
\end{itemize}
\bigskip
Step 3: Carefully track how the top and bottom portions of the printed text map onto the unfolded shape.
\bigskip
Step 4: Comparing all options:
\begin{itemize}
\item A: Correctly reflects the mirrored and inverted placement of letters after unfolding — valid.
\item Options B, C, D: Show incorrect letter orientation or positioning — invalid.
\end{itemize}

Final Answer:
\[
\boxed{A}
\]
