Wrong answer
If you draw the graph of the curve, you'll see that the answer is wrong... I think the answer is (a).

It seems that the true answer is 1/2 of choice a) (so none of the above). I explained how the answer is = 1/2 of option a) then stated that a) is the final answer.
Thanks a lot Brian!
