    If\[|z|\ge 3,\]then the least value of\[\left| z+\frac{1}{4} \right|\]is

    A) \[\frac{11}{2}\]                                

    B) \[\frac{11}{4}\]

    C) 3                                             

    D) \[\frac{1}{4}\]

    Correct Answer: B

    Solution :

    \[{{C}_{6}}{{H}_{12}}\left( g \right)={{p}_{1}}\]                    \[={{p}_{2}}-3{{p}_{1}}+{{p}_{1}}=30mm\]                     \[{{p}_{2}}-2{{p}_{1}}=30mm\] Hence,       \[{{\text{p}}_{\text{1}}}\text{=10mm, }{{\text{p}}_{\text{2}}}\text{=50mm}\]
