Answer:

b is the answer.......

Answer 2

The correct option is : a) both a and r are true and r is the correct explanation of the assertion

Assertion: the inner lining of intestine has tall epithelial cells.

In the inner lining of the intestines, tall epithelial cells can be found. The tall epithelium is present where absorption and secretion are done.

As the intestinal wall is involved with both secretion and absorption, the presence of tall epithelium can be found.

Reason : columnar epithelium facilitates absorption and secretion

Columnar epithelial cells, tall in structure are present in the lining of the intestines. Columnar cells are pillar-like cells and they help in absorption and secretion. Thus, the presence of columnar epithelium helps with secretion and absorption and is present in the inner lining of the intestines.
