Detailed Solution

The assertion (A) is correct. Succus entericus is formed by the secretions of goblet cells (mucus) and brush border cells (enterokinase, dipeptidases, nucleotidases, nucleosidases, etc.) in the intestine. This mix of secretions plays a role in digestion.

Reason (R) is incorrect. Cells of only small intestine allow the absorption of simple sugars.

Stomach also helps in absortion of some simple sugars.
