Explanation:

- The Integrated Child Development Services (ICDS) was launched to improve the health, nutrition, and development of children.

- It primarily targets children in the age group where early interventions can have significant benefits.

- Correct Answer: Option 2: 0-6 years

- The program focuses on children from birth up to six years.

- It provides services such as supplementary nutrition, immunization, and early education.

- Option 1: 0-10 years

- The ICDS program does not extend its services to children up to ten years.

- Option 3: 1-6 years

- This option excludes children under one year, which is a critical age group targeted by ICDS.

- Option 4: 1-10 years

- Similar to Option 3, but also inaccurately extends the age range beyond the ICDS scope.
