    Answer : Option B

    Explanation :

    ( 000216)1/3  = \( [\frac { 21 6} { 10^6 }] ^1/3\)

                           

                              =[\(\frac { 6*6*6 } { 10^2*10^2*10^2 } ]^1/3\)

               

                                =\( \frac {6 } { 10^2 }\)

                     

                                =\( \frac { 6} { 100 } \)

                   

                                =0.06
