b. Assertion is true, but Reason is false
c. Assertion is false, but Reason is true
d. Both assertion and reason are false​

Answer 1

Answer:

a

Explanation:

villi increase the surface area in intestine so it increases digestion

Answer 2

The correct option is- a. Both Assertion and Reason are true.

What are villi?

• Maximum absorption of nutrients takes place in the small intestine. It has villi that are numerous small projections present on the inner walls of the small intestine. Hence, the assertion is true.
• The thin walls of the villi facilitate the shorter diffusion route.
• The finger-like villi help in the efficient absorption of nutrients during the digestion process by increasing the surface area. Hence, the reason is also true.
