Detailed Solution

Concept: Less than six months old newborns have an undeveloped digestive system. Their GIT is unable to manufacture digestive enzymes, unlike that of kids or adults. Gastric juice's function is to coagulate or sour milk. In this way, it is absent in adults but available in newborn babies who consume milk.
To answer this question, first, we must understand the stomach condition and physiological conditions:
The child's tummies can just hold between 14 and 12 mugs of liquid. The gastric organs in the stomach have parietal cells, which make HCl and natural factors.The parietal cells begin to work just after birth. The gastric pH is under 4 for the original 7 to 10 days of life.
-Pepsinogen is an inactive enzyme that's buried by the gastric cells and gets converted into its active form.
-Lipase is an enzyme that's present in the digestive system and converts triglycerides into free adipose acids and alcohols.
-Rennin is a proteolytic emulsion blended by the stomach.
-Amylase promotes the hydrolysis of complex bounces into simple sugars.
-Maltas is responsible for the digestion of maltose.
-Nuclease is responsible for the digestion of nucleic acids.
Hence, the correct answer is option 1.
