Answer:

The correct answer will be option a and b.

Explanation:

The food is digested and absorbed in the small intestine, a long folded tube which lengths about 20 ft or 6m.  

The small intestine increases the surface area for food absorption as they have circular folding as well as the finger-like projections called villi and microvilli in the lumen of the intestine. These villi help in absorption of the nutrients from the intestine.

Thus, option a and b are the correct options.
