    \captionsetup{skip=1pt}%
    \includegraphics[width=\linewidth]{example-image}
    \caption{A}
  \end{subfigure}%
  \hfill
  \begin{subfigure}[t]{.48\textwidth}
    \includegraphics[width=\linewidth]{example-image}
    \caption{B}
  \end{subfigure}
  \caption{Example main caption}
\end{figure}
\end{document}
