A 5-year-old boy swallows a bottle of aspirin (salicylic acid) and is treated in the emergency room. The treatment produces a change in urine $\mathrm{pH}$ that increases the excretion of salicylic acid. What was the change in urine $\mathrm{pH}$ , and what is the mechanism of increased salicylic acid excretion?

A) Acidification, which converts salicylic acid to its HA form
B) Alkalinization, which converts salicylic acid to its $\mathrm{A}^{-}$ form
C) Acidification, which converts salicylic acid to its $\mathrm{A}^{-}$ form
D) Alkalinization, which converts salicylic acid to its HA form
