[Tex/LaTex] Two column document, 2X1 figure placement

Question

I need to place 3 figures in a two-column document, wherein the 3rd figure at the bottom needs to be centred! How can I do this?

I want something like this:

To do the same for 4 figures I have been using:

\begin{figure*} 
\begin{multicols}{2}
    \includegraphics[width=\linewidth]{1.eps}\par 
    \includegraphics[width=\linewidth]{2.eps}\par 
\end{multicols}
\begin{multicols}{2}
    \includegraphics[width=\linewidth]{3.eps}
    \includegraphics[width=\linewidth]{4.eps}
\end{multicols}
\caption{Here}
\end{figure*}

which works perfectly and I am able to get 4 figures aligned in the two-column document.

Answer 1

\documentclass[twocolumn]{article}
\usepackage{graphicx}

\begin{document}

\begin{figure*}
\centering 
\includegraphics[height=3cm]{example-image-a}\quad
\includegraphics[height=3cm]{example-image-b}\par\medskip
\includegraphics[height=3cm]{example-image-c}
\caption{a figure with three subfigures}
\end{figure*}

\end{document}
