The correct option is
A-4, B-2, C-3, D-1
Explanation
The public health system in India is organized into a tiered structure to ensure healthcare accessibility from the grassroots level to specialized urban centers. This hierarchy connects local village services to advanced district and city-level hospitals.
Statement-wise Analysis:
- A. Village Level (Matches with 4): At the village level, the health structure is represented by a Sub-Centre. It typically consists of a nurse (Auxiliary Nurse Midwife - ANM) and a Village Health Worker (often an ASHA worker). They are trained to deal with common illnesses and provide maternal and child care.
- B. PHC Level (Matches with 2): The Primary Health Centre (PHC) covers a cluster of villages in a rural area. It serves as the first contact point between the village community and a qualified Medical Officer.
- C. District Level (Matches with 3): The District Hospital functions as the secondary level of healthcare. It not only provides care but also supervises all the health centres (PHCs and Community Health Centres) within the district.
- D. Large Cities (Matches with 1): Large urban centers are equipped with specialized government hospitals and tertiary care institutions that offer advanced medical treatments and specialized surgeries not available at lower levels.
Key Takeaway:
The hierarchy of the Indian public health system flows as: Sub-Centre (Village) → Primary Health Centre (PHC) → Community Health Centre (CHC) → District Hospital → Specialized Hospitals (Cities).
