Of   the  four  choices  given after  the statements  choose  the one that  best describes  the two statements If   two  springs $S_{1}and{S}_2$ of   force constants  $k_{1 }and k_2$   respectively  are stretched by the same  force  ,it is found that  more  work is done on springs $S_1$ than on spring $S_2$. 
Statement I:  If  stretched  by the same amount  work done on $S_1$ will be more  than that  on  $S_2.$
Statement II:  $k_1<k_2$
