Using the formula M1V1 = M2V2, where M1 is the initial concentration, V1 is the initial volume, M2 is the final concentration, and V2 is the final volume, we can solve for V1.

M1V1 = M2V2
(18 M) V1 = (0.50 M) (500.0 mL)
V1 = (0.50 M) (500.0 mL) / (18 M)
V1 = 13.9 mL

Therefore, we need to dilute 13.9 mL of 18 M acid with distilled water to prepare 500.0 mL of 0.50 M acid, which is closest to answer choice D, 14 mL.
