## Core Concept
Asha workers are a critical component of India's rural healthcare infrastructure, functioning under the National Rural Health Mission (NRHM). They are community health workers instituted by the government of India's Ministry of Health and Family Welfare (MoHFW) as part of the National Rural Health Mission (NRHM). The role of an Asha worker is to act as an interface between the community and the public health system.

## Why the Correct Answer is Right
The Asha workers are primarily responsible for catering to the health needs of a specific population in rural areas. The correct answer, **1000-2500 population**, reflects the typical population range an Asha worker is designated to serve. Asha workers are chosen by the local community and are trained to provide basic health and medical care. They are pivotal in promoting health care services, especially in areas with low accessibility.

## Why Each Wrong Option is Incorrect
- **Option A:** This option is incorrect because it suggests a much larger population, which does not align with the designated population range for an Asha worker.
- **Option B:** This option suggests a smaller population range, which, although closer, does not accurately represent the standard population range an Asha worker is expected to cover.
- **Option D:** This option suggests an even larger population range than Option A, making it incorrect for the context of Asha workers' coverage.

## Clinical Pearl / High-Yield Fact
Asha workers are often considered the backbone of rural healthcare due to their role in bridging the gap between the community and healthcare services. A key point to remember is that Asha stands for "Accredited Social Health Activist," and these workers receive a small stipend for their services. Their responsibilities include facilitating access to health services, promoting health education, and providing basic health and nutrition information.

## Correct Answer: C. 1000-2500 population
