Problem 4: Additional rapid response to acidosis

Continuing with the previous question, an additional rapid response to metabolic acidosis kicks in at or below pH 7.14, which is:

A.	retention of OH- in the kidney.
B.	retaining HCO3- in the kidney.
C.	excreting H+ in the kidney.
D.	direct buffering action of the H2CO3 central intermediate.
E.	retaining CO2 in the lung.
