I agree.
With the equation v= √64h, you plug in 75 as h. Next, you multiply them to get 4,800. This would be √4,800.
Now, you solve that. the square root of 4.800 is 69.282032302755091741097853660235.
69.282032302755091741097853660235 is closer to the answer for D than any of the others, so D has to be the answer.
I hope this helps! :)
