Step 1: Understanding Assertion A:
Breastfeeding is one of the most recommended practices for infant health during the early stages of growth. It provides essential nutrients and promotes the overall health and development of the newborn. Doctors universally recommend it because it strengthens the infant's immune system and offers the right balance of nutrients during a critical growth phase.
Step 2: Understanding Reason R:
Colostrum, the first milk produced by the mother, is rich in antibodies and nutrients. These antibodies, such as Immunoglobulin A (IgA), are critical in providing passive immunity to the newborn, helping them fight infections until their immune system is fully developed. This makes colostrum a crucial component of the breastfeeding process, supporting the baby’s immune system.
Step 3: Evaluating the Statements:
- Assertion A is correct because breastfeeding during the initial stages is indeed recommended for infant health and development. - Reason R is also correct because colostrum contains essential antibodies that help in developing immunity in the newborn.
Step 4: Conclusion:
The reason mentioned in R accurately explains the assertion A, as both statements align with the benefits of breastfeeding and colostrum.
Answer: The correct option is Option 1: Both A and R are correct, and R is the correct explanation of A.

Consider a water tank shown in the figure. It has one wall at \(x = L\) and can be taken to be very wide in the z direction. When filled with a liquid of surface tension \(S\) and density \( \rho \), the liquid surface makes angle \( \theta_0 \) (\( \theta_0 < < 1 \)) with the x-axis at \(x = L\). If \(y(x)\) is the height of the surface then the equation for \(y(x)\) is: (take \(g\) as the acceleration due to gravity)
A constant voltage of 50 V is maintained between the points A and B of the circuit shown in the figure. The current through the branch CD of the circuit is :
