    A)  \[2\sqrt{3}\]               

    B)  \[2\sqrt{6}\]

    C) 16                   

    D)          32

    Correct Answer: B

    Solution :

    4 : m : 6 is in continued proportion hence, \[\frac{4}{m}=\frac{m}{6}\] \[\Rightarrow \]            \[{{m}^{2}}=24\] \[\Rightarrow \]            \[m=2\sqrt{6}\]
