    B)                         \[\frac{17}{11}\]                             

    C)                         \[\frac{170}{11}\]                                           

    D)                         \[\frac{17}{110}\]

    Correct Answer: C

    Solution :

    \[\sqrt{\frac{0.289}{0.00121}}=\sqrt{\frac{0.28900}{0.00121}}=\sqrt{\frac{28900}{121}}\] \[=\frac{\sqrt{28900}}{\sqrt{121}}=\frac{170}{11}\]
