Drug A and B are both eliminated from the body by liver. The clearance of A is 1.5 l/min (almost egual to the liver blood flow), the clearance of B is 0.1 l/min. What will be the change of the drugs clearance if rifamp is added to the patient's regimen?

a. The clearance of A and B will be increased
b. The clearance of A and B will be decreased
c. The clearance of A will be unchanged and clearance of B will be increased
d. The clearance of B will be unchanged and clearance of A will be increased
