B Correct answer
Explanation

The free fatty acids and monoglycerides form micelles that migrate towards the brush border membrane. The micelle permits fat components to be soluble in water. Because bile salts have a hydrophobic or water repelling region and a hydrophilic or water attracting region, the micelle is formed with bile salts arranged around the outside with hydrophobic ends facing inside and hydrophobic fatty acids, monoglycerides, phospholipids and cholesterol as well as the fat soluble vitamins A, D, E and K in the centre.
