Answer 1

The wall of the large intestine lacks villi, has teniae coli, and has haustra, which corresponds to option b) lacks, has, has.

Step-by-step explanation:

The unique aspects of the wall of the large intestine are that it lacks villi, it has teniae coli, and it has haustra. Hence, the correct answer to the student's question is option b) lacks, has, has.

Teniae coli are three bands of smooth muscle in the muscularis of the large intestine, which cause the colon to form pouches known as haustra, giving the colon a wrinkled appearance. Unlike the small intestine, the large intestine's wall does not contain villi, which are present in the small intestine to increase surface area for absorption.
