Answer 1

Correct option  (d) A and R are false

Explanation:

Bile (gall) is a bitter-tasting greenish yellow alkaline fluid produced by the liver stored in the gall bladder and secreted into the duodenum of vertebrates. It assists the digestion and absorption of fats by the action of bite salts. which chemically, reduce fatty, substance s and decrease the surface tension of tat droplets so that they are broken down and emulsified. Bile may,also stimulate gut muscle contraction (peristalsis). bile also contains the bile pigments, bilirubin and biliverdin,which are produced by the breakdown of the blood pigment haemoglobin.
