**Core Concept**
The principles of primary health care (PHC) emphasize a holistic approach to health, focusing on community-based care, disease prevention, and health promotion. PHC aims to provide accessible, comprehensive, and equitable care to individuals and communities, addressing their physical, mental, and social health needs.

**Why the Correct Answer is Right**
The correct answer is one that contradicts the fundamental principles of PHC. PHC prioritizes community involvement, intersectoral collaboration, and a multidisciplinary approach to care. It emphasizes the importance of addressing the social determinants of health, such as education, employment, and environmental factors, to promote health and prevent disease.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because PHC does not focus solely on curative care, but rather on preventive and promotive care as well. PHC aims to address the root causes of health problems, rather than just treating symptoms.
**Option B:** This option is incorrect because PHC does not require a high-tech, hospital-based approach to care. In fact, PHC often involves community-based care and the use of low-cost, low-tech interventions.
**Option C:** This option is incorrect because PHC does not prioritize individual care over community care. PHC recognizes that health is a social and community issue, and that individual health is closely tied to the health of the community.

**Clinical Pearl / High-Yield Fact**
One key principle of PHC is the concept of "intersectoral collaboration," which involves working with other sectors, such as education, agriculture, and transportation, to address the social determinants of health and promote health.

**Correct Answer: None**
