## Core Concept
The Anganwadi worker plays a crucial role in the Integrated Child Development Services (ICDS) program in India, aiming to provide basic health, nutrition, and early childhood education to children and their mothers. The role encompasses various responsibilities, including growth monitoring, supplementary nutrition, health and nutrition education, and immunization.

## Why the Correct Answer is Right
The correct statement regarding an Anganwadi worker needs to be identified based on their roles and qualifications. Typically, an Anganwadi worker is a local woman with a minimum educational qualification of Class 10, appointed to work in her own village or locality. She is responsible for providing a package of services including supplementary nutrition to children and pregnant and lactating mothers, growth monitoring, health education, and immunization.

## Why Each Wrong Option is Incorrect
- **Option A:** Without specific details on what option A states, it's challenging to directly refute it. However, if it aligns with known responsibilities or characteristics of an Anganwadi worker, such as being a woman from the local community with a certain level of education, then it would be correct.
- **Option B:** Similarly, without specifics, we can't directly address why B is incorrect. If B suggests that an Anganwadi worker is a graduate or needs to have a medical background, this could be incorrect as the typical requirement is not that stringent.
- **Option C:** Again, specifics are needed. If C mentions something about the worker's responsibilities or eligibility that aligns with the ICDS guidelines, then it might not be incorrect.
- **Option D:** This option is stated as the correct answer but without context, it's hard to validate. If D claims something that contradicts known facts about Anganwadi workers, such as their qualifications, age range, or responsibilities, then it would be incorrect.

## Clinical Pearl / High-Yield Fact
A key point to remember is that Anganwadi workers are crucial for implementing grassroots health and nutrition interventions. They typically need to have completed Class 10 and are selected from and work within their own communities, making them accessible and relatable to the population they serve.

## Correct Answer: D.
