**Core Concept:** The Social Physician concept is a philosophy that emphasizes the importance of addressing social determinants of health in providing healthcare services. The concept recognizes that healthcare cannot be separated from social and economic conditions that shape health outcomes.

**Why the Correct Answer is Right:** The correct answer, Option C (Alma Ata Declaration), refers to a key event in the development of the Social Physician concept. The Alma Ata Declaration, issued in 1978 at the International Conference on Primary Health Care, highlighted the importance of addressing social determinants of health in healthcare provision. This declaration led to the establishment of the World Health Organization's (WHO) Alma Ata Programme, which focused on community-based primary healthcare and emphasized the role of healthcare professionals in addressing social inequalities and improving health outcomes.

**Why Each Wrong Option is Incorrect:**

A. The correct answer is not Option A (WHO Constitution) as it primarily focuses on the organizational structure and functions of the World Health Organization, rather than the Social Physician concept.

B. Option B (Public Health Inequalities Declaration) is incorrect because it is a more recent event (2007) and does not directly contribute to the development of the Social Physician concept.

C. Option C (Alma Ata Declaration) is the correct answer, as mentioned above, and highlights the importance of addressing social determinants of health in healthcare provision.

D. Option D (Global Strategy on Diet, Physical Activity and Health) is incorrect because it focuses on promoting healthy lifestyle choices, rather than the Social Physician concept and its emphasis on addressing social determinants of health.

**Clinical Pearl:** The Social Physician concept is crucial for healthcare professionals to understand the broader context of health and disease, recognizing that social determinants shape health outcomes. By addressing these determinants, healthcare professionals can improve health equity and contribute to reducing health disparities.
