To solve this equation, follow the order of operations (PEMDAS/BODMAS):

First, divide (9) by (5/4):
9 / (5/4) = 9 * (4/5) = 36/5

Next, multiply (36/5) by (7/9):
(36/5) * (7/9) = (36 * 7) / (5 * 9) = 252/45

Then, multiply (252/45) by (-5):
(2552/45) * (-5) = -2520/45

Finally, divide (-2520/45) by (7/2):
(-2520/45) / (7/2) = (-2520/45) * (2/7) = -5040/315 = -16

So, the answer is B. -8.
