Answer 1

The correct option is A I,III and IV are incorrect

Absorption of carbohydrates takes place in the duodenum, first part of the small intestine. Water-soluble end products of food can be directly absorbed into the bloodstream from the intestine by both passive and active mechanisms. The majority of absorption of water and minerals takes place through the large intestine. Buccal cavity acts as a site of absorption of glucose directly into the bloodstream. The large intestine is the site of absorption of about 80% of the total water present in the hydrolyzed food.

Thus, the correct answer is 'I, III and IV are incorrect'.
