Question

Assertion (A): Breast feeding during the initial period of infant growth is necessary for bringing up a healthy baby. Reason (R): Colostrum contains several antibodies, especially IgA type.

• A. Both (A) and (R) are true. (R) is the correct explanation for (A)
• B. Both (A) and (R) are true. (R) is not the correct explanation for (A)
• C. (A) is true. But (R) is false
• D. (A) is false. But (R) is true

Hint:

Colostrum = "First milk" = Passive immunity for the infant via IgA.

Answer 1

The Correct Option is A

Step 1: Read both parts.
Assertion (A) says breast feeding in the early days is needed for a healthy baby. Reason (R) says colostrum has many antibodies, mainly of the IgA type. We judge each and check the link.

Step 2: Check the Assertion.
A newborn has a weak immune system and cannot fight germs well on its own. Mother's milk helps protect it, so early breast feeding really is important. So (A) is true.

Step 3: Know what colostrum is.
Colostrum is the thick yellowish first milk produced in the first few days after birth. It is special because it is packed with protective substances.

Step 4: Check the Reason.
Colostrum is rich in antibodies, and the main type is IgA. These antibodies guard the baby's gut and surfaces against germs. So (R) is true.

Step 5: Test the link.
The baby is healthier because the colostrum gives it ready-made antibodies. So the IgA in colostrum is exactly why early feeding keeps the baby healthy.

Step 6: Decide the option.
Both are true and the reason correctly explains the assertion.
\[ \boxed{\text{Both (A) and (R) are true. (R) is the correct explanation for (A)}} \]
