 56..i am getting constant sequence(which is the key ans)

 for any arbitary integer k, fk (x)=k if   0<x<1/k
                                            = 0 otherwise

integration of fk over its domain is itgretate from 0 to 1/k of kdx=1.

so the sequence will be 1+1+1+1....a cosntant sequence


guys please help me with the working of question 57 of 2012 ..i am getting option a though the ans is c.
