C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Once in the bloodstream, the enzyme lipoprotein lipase breaks down the triglycerides of the chylomicrons into free fatty acids and glycerol. These breakdown products then pass through capillary walls to be used for energy by cells or stored in adipose tissue as fat.

Detailed explanation-2: -The digestive process has to break those large droplets of fat into smaller droplets and then enzymatically digest lipid molecules using enzymes called lipases . The mouth and stomach play a small role in this process, but most enzymatic digestion of lipids happens in the small intestine.

Detailed explanation-3: -Lipase is an enzyme that breaks down triglycerides into free fatty acids and glycerol by catalyzing the hydrolysis of the ester bonds in triglycerides.[5] Lipases are present in pancreatic secretions and participate in fat digestion and metabolism.
