Verbal Section: CR : Confusion

Hi Experts,

I am just a beginner, so please pardon if I did not frame/format the question correctly.
I came across below question (attached the screenshot), please let me know if I should type it in:

The solution suggested is option C. I am confused on why Option D is not correct. It clearly says that the
‘Research shows that people who practice defensive driving are considerably less likely to get into a car accident.

Is not option D stating exact the same ?

Thanks in advance.
