Answer :
Option (A)
Bile juice is produced in the liver, stored in gall bladder and released in the small intestine for the digestion of fats. The bile juice consists of water, bile salts and bilirubin in 97%, 0.7% and 0.2% respectively. Bile salts are amphiphilic molecules viz.
it contains both hydrophobic and hydrophilic groups. The bile salts form micelles by surrounding the fats/ lipids with their hydrophobic group inside and hydrophilic group outside . These micelles increase the surface area for digestion of lipids by the lipase viz. pancreatic lipase which is produced by the pancreas
