    A) \[\pm 11\]                     

    B)        \[\pm 8\]                       

    C) \[\pm 6\]                       

    D)        \[\pm 7\]                       

    E) \[\pm 5\]

    Correct Answer: C

    Solution :

    \[[{{(11025\div 9)}^{\frac{1}{2}}}+{{(8019\div 11)}^{\frac{1}{2}}}]={{?}^{2}}+26\] or,\[{{?}^{2}}=[{{(1225)}^{\frac{1}{2}}}+{{(729)}^{\frac{1}{2}}}]-26\] \[=(35+27)-26=62-26=36\] \[\therefore \]\[?=\pm \sqrt{36}=\pm 6\]
