In LaTeX, everything works fine with subfigure package, only one trouble is coming;
The subcaptions are placed a little towards left from the centre of two figures side by side, which doesnt loook good,,, I have tried everything using nooneline, hang , centrelast etc. but no desired result is coming . Kindly suggest me how could i move either the captions towards centre of figures or the figures such that subcaptions comes in centre.
[Tex/LaTex] Subcaption not in the centre in subfigure package

Change the representation for the subfigure counter by redefining \thesubfigure:
\documentclass[a4paper,oneside,10pt]{scrartcl}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{subcaption}
\renewcommand\thesubfigure{\roman{subfigure}}
\begin{document}
\begin{figure}
\centering
\begin{subfigure}[b]{0.3\textwidth}
\centering
{\rule{3cm}{2cm}}
\caption{Picture 1}
\label{sfig:a}
\end{subfigure}%
\begin{subfigure}[b]{0.3\textwidth}
\centering
{\rule{3cm}{2cm}}
\caption{Picture 2}
\label{sfig:b}
\end{subfigure}
\caption{Two picures; a black picture (\subref{sfig:a}) and another black picture (\subref{sfig:b}).}
\end{figure}
\end{document}
The subfigure package provides a \subfigure command, not an environment.
The syntax is
\subfigure[<optional argument>]{mandatory argument}
what happens with your code is that the mandatory argument is \centering. Chaos ensues.
\documentclass[a4paper, 11pt, oneside]{report}
\usepackage[square, numbers, comma, sort&compress]{natbib}
\usepackage{amsmath,graphicx,amssymb,braket,xcolor,subfigure,upgreek,bbold}
\usepackage{esint}
\begin{document}
\begin{figure}
\centering
\subfigure[Fig.\ A]{\includegraphics[width=3cm]{example-image}\label{fig:Ex_Im}}
\subfigure[Fig.\ B]{\includegraphics[width=6cm]{example-image}\label{fig:Ex_Im2}}
\caption{This is the caption.}\label{fig:Label}
\end{figure}
\end{document}
However, subfigure is obsolete and you should prefer either subfig or subcaption.
With the former package, the syntax is
\documentclass[a4paper, 11pt, oneside]{report}
\usepackage[square, numbers, comma, sort&compress]{natbib}
\usepackage{amsmath,graphicx,amssymb,braket,xcolor,subfig,upgreek,bbold}
\usepackage{esint}
\begin{document}
\begin{figure}
\centering
\subfloat[Fig.\ A]{\includegraphics[width=3cm]{example-image}\label{fig:Ex_Im}}\quad
\subfloat[Fig.\ B]{\includegraphics[width=6cm]{example-image}\label{fig:Ex_Im2}}
\caption{This is the caption.}\label{fig:Label}
\end{figure}
\end{document}
With the latter, you can use \subcaptionbox:
\documentclass[a4paper, 11pt, oneside]{report}
\usepackage[square, numbers, comma, sort&compress]{natbib}
\usepackage{amsmath,graphicx,amssymb,braket,xcolor,subcaption,upgreek,bbold}
\usepackage{esint}
\begin{document}
\begin{figure}
\centering
\subcaptionbox{Fig.\ A\label{fig:Ex_Im}}{\includegraphics[width=3cm]{example-image}}\quad
\subcaptionbox{Fig.\ B\label{fig:Ex_Im2}}{\includegraphics[width=6cm]{example-image}}
\caption{This is the caption.}\label{fig:Label}
\end{figure}
\end{document}
I'd prefer subcaption, but the class you're using might not like it; in this case, go with subfig.
