Which digestive fluid breaks down fats? a. bile b. chyme c. amylase d. pepsin

The answer would be A bile.

But i just wanted to point sth out

Bile causes fat globules to break down or be emulsified into minute, microscopic droplets.

Emulsification is not digestion per se, but is of importance because it greatly increases the surface area of fat, making it available for digestion by lipases, which cannot access the inside of lipid droplets.

Bile doesn’t have enzymes so it doesn’t “digest” fats or break them down into their components it just emulsifies them.
