about jagged arrays in c#

i have a question, please reply me.
 
if a one dimensional jagged array having three inner arrays,are two two dimensional and a one dimensional array,write a program
to initialising and displying the jagged array?


for example:
             jagged array A having,  A[0]={ {1,2,3},{9,8,7}};
                                             A[1]={1,2,3,4};
                                             A[2]={{4,5,6,7},{1,2,8,9},{2,4,6,8}};
