The primary level of healthcare in Assam is provided through a network of:

Sub-centers, Primary Health Centers (PHCs), Community Health Centers (CHCs)
District hospitals and medical colleges
Private clinics and pharmacies
Super-specialty hospitals

The correct answer is: a) Sub-centers, Primary Health Centers (PHCs), Community Health Centers (CHCs).

Sub-centers, Primary Health Centers (PHCs), and Community Health Centers (CHCs) are the three levels of primary healthcare in Assam. Sub-centers are the first point of contact for people in rural areas, and they provide basic healthcare services such as immunization, family planning, and treatment of minor illnesses. PHCs are located in larger villages and towns, and they provide a wider range of services, including antenatal care, postnatal care, and treatment of common diseases. CHCs are located in district headquarters, and they provide the most comprehensive range of primary healthcare services, including emergency care, surgery, and specialized treatment.

District hospitals and medical colleges provide secondary and tertiary healthcare services. Private clinics and pharmacies provide a range of healthcare services, but they are not part of the government’s primary healthcare system. Super-specialty hospitals provide the highest level of healthcare services, but they are not accessible to most people in Assam.
