Correct option (c) Both A and R are not correct.
Explanation:
Absorption of substances takes place in different parts of the alimentary canal, like mouth, stomach, small intestine and large intestine. However, maximum absorption occurs in the small intestine. Hence small intestine is the principal organ for absorption of nutrients. The digestion is completed here and the final products of digestion such as glucose, fructose, fatty acids, glycerol and amino acids are absorbed through the mucosa into the blood stream and lymph. Absorption of water, single sugars and alcohol, etc. takes place in stomach. In larger intestine, absorption of water, some minerals and drugs takes place.
