**Core Concept**
Peripheral level health workers play a crucial role in providing primary healthcare services in rural and underserved areas. These workers are typically employed by government health departments and are responsible for delivering basic healthcare services, health education, and community outreach.

**Why the Correct Answer is Right**
Gram Sevak is a village-level worker employed by the panchayat (local self-government body) to oversee rural development, not specifically healthcare. While Gram Sevaks may have some involvement in health-related activities, their primary focus is on development and administration, not healthcare delivery. In contrast, Anganwadi workers, DAIS (Dais, or traditional birth attendants), and VHNS (Village Health Nutrition Sanitation Workers) are all specifically involved in health-related activities, making them peripheral level health workers.

**Why Each Wrong Option is Incorrect**
**Option A:** Anganwadi workers are indeed peripheral level health workers, responsible for providing healthcare services, nutrition education, and child development programs to rural communities.
**Option B:** DAIS (Dais) are traditional birth attendants who provide basic obstetric care and health education to women in rural areas, making them peripheral level health workers.
**Option D:** VHNS (Village Health Nutrition Sanitation Workers) are employed by the government to promote health, nutrition, and sanitation in rural areas, placing them squarely in the category of peripheral level health workers.

**Clinical Pearl / High-Yield Fact**
Peripheral level health workers are essential for bridging the gap in healthcare access between urban and rural areas. Their role in providing basic healthcare services, health education, and community outreach is critical for improving health outcomes in underserved populations.

**✓ Correct Answer: C. Gram Sevak**
