Answer 1

benzoic acid is used

Answer 2

Answer:

(A) Benzoic acid is the correct option

Explanation:

The drug which is used for the treatment of urinary tract infections consists of hyoscyamine, hexamethylenetetramine, phenyl salicylate, methylene blue, and benzoic acid.

Benzoic acid is used to lower the PH in urine so that hydrolysis of hexamethylenetetramine can take place. On hydrolysis, hexamethylenetetramine forms formaldehyde which helps in killing the bacteria.
