The correct answer is: b) Primary Health Centers (PHCs).
Primary Health Centers (PHCs) are the first point of contact for people seeking healthcare in rural and remote areas. They provide basic healthcare services such as immunization, family planning, and maternal and child health care. PHCs also refer patients to higher-level facilities for specialized care.
District Hospitals are larger hospitals that provide a wider range of services than PHCs. They are located in district headquarters and provide secondary and tertiary care.
Sub-centers are small health facilities that are located in remote areas. They provide basic healthcare services such as immunization, family planning, and maternal and child health care. Sub-centers are staffed by a health worker and a midwife.
Super-specialty Hospitals are the highest level
