Detailed Explanation:

The Healthy People Initiative’s overarching goal is comprehensive health promotion and disease prevention.

Option A: Support health promotion and disease prevention across the lifespan

This is the primary aim of the Healthy People Initiative, which sets national health objectives to improve the health of all Americans.

Option B: Provide each state with individualized plans for improving vaccination rates

This may be part of health initiatives but is not the central focus of Healthy People.

Option C: Reduce the spread of infectious disease and preventpandemics

While disease prevention is a focus, Healthy People addresses a broader range of health topics beyond infectious diseases.

Option D: Allocate funding to prevent disparities related to social determinants of health

Addressing disparities is one objective, but funding allocation is not the core mission.
