    A)  \[\frac{1}{\sqrt{2}}s\]                                  

    B)  \[2\sqrt{2}s\]                                   

    C)  \[2s\]                                  

    D)  1

    Correct Answer: C

    Solution :

    Let       \[\frac{2}{5}\] \[\frac{3}{5}\] \[\frac{3}{7}\] According to question \[\frac{3}{4}\] \[\frac{R}{5}\]  \[\frac{4}{5}\] \[\frac{5}{6}\]  \[\frac{6}{7}\]                 \[\frac{1}{86400}{{/}^{0}}C\]    \[\frac{1}{43200}{{/}^{0}}C\]                 \[\frac{1}{44400}{{/}^{0}}C\]       \[\frac{1}{28800}{{/}^{0}}C\]
