Bile helps in the digestion of fat through
a)	Emulsification	b)	Alkalinity	c)	Forming micelles	d)	All of these

(d)

Bile contains no digestive enzymes, yet it plays an important role in fat digestion. It intensifies the ‘mixing contractions’ of intestinal wall. The organic salts of bile reduce the surface tension of fat globules and suspend them in water of digestive juice.  It is emulsification of fats. It facilitates easy action of pancreatic juice on fats.  They also help in formation of micelles, which help to transport of all end-products of fat digestion from intestinal lumen to absorptive cells.  The inorganic bile salts import alkalinity to chyme and inactivate gastric pepsin.
