In an experiment, a researcher infuses a solution of conjugated bile acids into the portal vein of a rat such that their normal concentration is approximately doubled

He collects samples of hepatic bile from the rat before and after the infusion. Before the infusion, the concentrations of bile acids (BA), phosphatidylcholine (PC), and cholesterol (chol) are 30, 9, and 3 units per mL. What would be the predicted concentrations of PC and chol in the bile following the BA infusion?

A. PC: 9; chol: 3
B. PC: 18; chol: 3
C. PC: 9; chol: 6
D. PC: 18; chol: 6
E. PC: 3; chol: 9
