## **Core Concept**
The Integrated Child Development Services (ICDS) is a government program in India aimed at providing nutritional support and promoting the health and well-being of children and their mothers. The program specifically targets children under the age of 6 years, with a focus on those under 3 years, and pregnant and lactating mothers. For children under 1 year, the nutritional needs are critical for growth and development.

## **Why the Correct Answer is Right**
The correct answer, **B. 700 kcal & 20-25 g protein**, reflects the nutritional guidelines provided under the ICDS for children less than 1 year of age. This recommendation is designed to support the rapid growth and development that occurs during infancy. The caloric and protein requirements are tailored to meet the needs of this age group for optimal growth.

## **Why Each Wrong Option is Incorrect**
- **Option A:** 500 kcal & 10 g protein. This option provides insufficient calories and protein for the growth and developmental needs of children under 1 year.
- **Option C:** 800 kcal & 30 g protein. While this might seem adequate, the specific recommendation under ICDS for children under 1 year is more aligned with option B.
- **Option D:** 900 kcal & 35 g protein. This option exceeds the recommended nutritional requirements for children under 1 year as per the ICDS guidelines.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the ICDS provides **take-home rations** or **supplementary nutrition** to children and pregnant/lactating women, aiming to bridge the nutritional gap. For children under 6 years, the focus is on providing supplementary nutrition to support growth and development, particularly in vulnerable populations.

## **Correct Answer:** B. 700 kcal & 20-25 g protein
