@ shalan 
in the frst ques option no b turns out to be the correct option . beacuse hookes law works in the limit of elastic limit , so, if elastic fatigue will be their , it will not obey the hookes law . 
in the 2nd ques option no a probably turns out to be the correct option

F= -kx 
so, kindly mention what is r ?? 
here x is the displacement produced .
