Remove A, D and E for redundancy.
It looks as though choice B implies that the rate fell on a particular time in the last ten years. This is logically wrong. The drop in the rate is over a period and hence could be gradual or even erratic, but finally reaching the said the point at the end of the given period.
C says that much by using the present perfect 'has fallen'. C is also more forthright in expressing the increase as 'has more than doubled".
C is the correct choice.
