Primary health care is guided by key principles like equitable distribution, community participation, appropriate technology, and inter-sectoral coordination.

Explanation of options: (a) ✔ Inter-sectoral Coordination – Involves collaboration between different sectors to improve health. (b) ✘ Eliminating Technology – Not a principle; primary care promotes using appropriate technology. (c) ✔ Community Participation – Empowers people to take part in their own health care decisions. (d) ✔ Equitable Distribution – Ensures health care services are fairly available to all.
