While it is indeed true that the small intestine contains multiple tube-like glands, the reason provided, stating that these glands secrete DNAse and RNAse enzymes into the intestinal juice, is incorrect. The small intestine primarily secretes enzymes such as amylase, lipase, and proteases, which are involved in the digestion of carbohydrates, fats, and proteins, respectively. DNAse and RNAse enzymes are more commonly associated with the breakdown of nucleic acids, but their secretion is not a characteristic feature of the glands in the small intestine. Therefore, although both the assertion and reason are true, the reason does not provide a correct explanation for the assertion. Hence, the correct answer is option 2.
