**Core Concept**
The Infant Mortality Rate (IMR) is a key indicator of a country's or region's overall health and well-being. It is the number of deaths of infants under one year of age per 1000 live births in a given year. The correlation between IMR and Socio Economic status (SES) is well established, with lower SES often being associated with higher IMR.

**Why the Correct Answer is Right**
The relationship between IMR and SES is complex and multifactorial. Lower SES is associated with reduced access to healthcare, poor living conditions, inadequate nutrition, and increased exposure to environmental hazards. These factors contribute to a higher risk of infant mortality. Additionally, lower SES is often linked to lower levels of education, which can lead to reduced awareness of healthy behaviors and delayed seeking of medical care.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incomplete and does not provide a clear answer.
* **Option B:** This option is not relevant to the correlation between IMR and SES.
* **Option C:** This option is incorrect as it does not accurately depict the relationship between IMR and SES.

**Clinical Pearl / High-Yield Fact**
The correlation between IMR and SES is often described by the "Social Determinants of Health" framework, which highlights the importance of addressing social and economic factors in improving health outcomes.

**Correct Answer: D. A scatter plot showing a positive correlation between IMR and SES.**
