Dear Student,

Option 4 is correct. Three statements (1, 2, 4) are correct.
Explanation:
Only statement 3 is wrong: Principal organ of absorption of nutrients is small intestine (instead of stomach).

The rest of the statements are briefly explained below:
1) Lysozyme is the enzyme secreted by submucosal glands.
2) Renin helps in coagulation of milk, after which pepsin acts on it for digestion. Renin is prodcued by chief cells present in the stomach of infants.
4) Serosa is the outermost layer of the alimentary canal.

Hope this will help you.
Regards,
