Which single statement about fat digestion and absorption is correct?

Options:
A. After absorption, both medium chain triglycerides (MCT) and long chain triglycerides enter the lymphatic system.
B. The products of complete digestion of triglycerides (triacylglycerols) can form mixed micelles with pancreatic cholesterol and phospholipids and this decreases absorption

D. Triglycerides (triacylglycerols) must be emulsified and digested before the fatty acids can be transported
E. After absorption, medium chain triglycerides (MCT) enter the lymphatic system, whereas long chain triglycerides enter the portal blood system.
F. Absorption of fatty acids in the intestine occurs primarily through the FABP and FAT/CD36 transport proteins in the proximal duodenum
G. Absorption of fatty acids in the intestine occurs mainly through FABP and FAT/CD36 transport proteins in the enterocytes of the mid jejunum.
