Actually, both Options A and B are correct. Option C is incorrect as bile breaks down only fats into smaller droplets, which is known as emulsification of fats. Liver secretes bile juice which is stored in the gall bladder. Fats are then broken down into fatty acids and glycerol. I request the Admin of SOF to kindly include an option of Both A and B in the following question, as both A and B are correct whereas Option c is incorrect.
