    Correct Answer: A

    Solution :

                     \[(n-1){{d}^{1}}n{{s}^{2}}\] shows III B group \[(n-1){{d}^{2}}n{{s}^{2}}\]shows IV B group \[(n-1){{d}^{3}}n{{s}^{2}}\]shows V B group \[(n-1){{d}^{5}}n{{s}^{2}}\]shows VI B group \[\left. \begin{matrix}    (n-1){{d}^{6}}n{{s}^{2}}  \\    (n-1){{d}^{7}}n{{s}^{2}}  \\    (n-1){{d}^{8}}n{{s}^{2}}  \\ \end{matrix} \right\}\] Shows VIII group \[(n-1){{d}^{10}}n{{s}^{1}}\] shows I B group
