    In CsCI type structure, the coordination number of \[{{D}_{k}}=\left| \begin{matrix}    a & {{2}^{k}} & {{2}^{16}}-1  \\    b & 3({{4}^{k}}) & 2({{4}^{16}}-1)  \\    c & 7({{8}^{k}}) & 4({{8}^{16}}-1)  \\ \end{matrix} \right|,\] and \[\sum\limits_{k=1}^{16}{{{D}_{k}}}\]respectively are

    A)  6, 6                       

    B) 6,8

    C)  8,8                        

    D) 8,6

    Correct Answer: C

    Solution :

    The coordination number is 8:8 in\[{{(y-2)}^{2}}=(x-1),\] The coordination number is 6:6 in \[x=1+xy\frac{dy}{dx}+\frac{{{(xy)}^{2}}}{2!}+{{\left( \frac{xy}{dx} \right)}^{2}}+\frac{{{(xy)}^{3}}}{3!}{{\left( \frac{dy}{dx} \right)}^{3}}\]
