Answer:
option c is correct

Answer:
Explanation:
Columnar epithelial cells:
Epithelial cells in the shape of columns make up the columnar epithelium. The columnar epithelium is made up of cells that are taller than they are wide. Its width is roughly equal to its height. Each cell has an extended nucleus, which is frequently located close to the base.
Function of columnar epithelial cells:
Simple columnar epithelial cells' primary role is defense. For instance, the stomach and digestive tract's epithelium acts as a barrier that is impervious to germs but permeable to any essential ions.
Glandular cells:
A specific kind of cell that produces mucus and is present in the tissue lining the inner portion of the cervix. Pap tests may reveal abnormal glandular cells, which could be an indication of cancer or another serious illness.
Function of Glandular cells:
The production and release of various secretory products, including hormones, saliva, breast milk, digestive enzymes, and perspiration, is the glandular epithelium's primary role.
Columnar epithelial cells are much longer than broad
The most frequent configuration of columnar epithelial cells is in a single layer and they are taller than wide, resembling a stack of columns in an epithelial layer. Figure shows how the columnar epithelial cells of the digestive system appear to have their nuclei lined up at the base of the cells. These cells take in substances from the digestive tract's lumen and prepare them for absorption into the body via the lymphatic and circulatory systems.
Hence, Option (b) is the correct answer.
