Question

Assertion: Large intestine also shows the presence of villi like small intestine.
Reason: Absorption of water and some salts are done by the large intestine.
A. Both assertion and reason are correct and reason is the correct explanation for assertion.
B. Both assertion and reason are correct and reason is the correct explanation for assertion.
C. Assertion is correct but reason is not correct.
D. Assertion is not correct but reason is correct.

Answer 1

The tubular section of the alimentary canal that runs from the stomach to the anus is known as the intestine. Most chemical digestion activities take place in the gut, which is also where digested food molecules are either absorbed for use by the body or gathered in faeces for disposal. The small intestine is the section of the gut that connects to the stomach in its anterior region. It is followed by the large intestine, which is a shorter, broader tract that ends at the anus.

Complete solution:
Let us look at the options to find the correct answer.
Option A is not correct because the large intestine does not have villi. Hence, the assertion is wrong.
Option B is not correct based on the same grounds as described above.
Option C is also not correct based on the same grounds as described above.
Option D is correct because the large intestine does not have villi but it helps in the absorption of water and some salts through its epithelium. So, the assertion is wrong but the reason is a correct statement in terms of factuality.

Therefore, Option D. Assertion is not correct but reason is correct, is the correct answer.

Note:
The large intestine is significantly larger than the small intestine and consists of a columnar epithelium lacking villi, and it travels through your gut, or abdomen, in a much more straight line. The large intestine's job is to collect water and salts from stuff that hasn't been digested as food and to eliminate any waste items that have remained. The majority of digestion and absorption has already occurred by the time food combined with digestive fluids reaches your big intestine.
