Solution

The correct option is C Chylomicrons are small lipoprotein particles that are transported from the intestine through blood capillaries to various tissues.
In the intestinal mucosal cells, after absorption, the triglycerides and cholesterol are re-esterified to form chylomicrons. The chylomicrons in turn are secreted into intestinal lymph, enter the blood stream through the thoracic duct and bind to the wall of capillaries in adipose and skeletal tissue.
So, option C is the correct answer.
