• A. 5
• B. 6
• C. 7
• D. 8

Answer 1

Answer: (B)

6

Answer is option B i.e. "6.0"
Urine pH is of diagnostic importance. The kidneys maintain normal acid-base balance primarily through the reabsorption of sodium and the tubular secretion of hydrogen and ammonium ions.
Urine becomes increasingly acidic as the amount of sodium and excess acid retained by the body increases. The glomerular filtrate of blood is usually acidified by the kidneys from a pH of approximately 7.4 to a pH of about $pH=6.0$ in the urine.
