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,
