What are the top five killers of adults?

The correct choice highlights the leading causes of death among adults, which are well-documented in public health data. Coronary artery disease is a form of cardiovascular disease that remains the leading cause of mortality, as it can lead to heart attacks. Cancer encompasses a variety of malignancies that collectively cause a significant number of deaths, varying by type and demographic factors. Lower respiratory diseases, including chronic obstructive pulmonary disease (COPD) and pneumonia, rank highly due to factors such as smoking and infections, contributing substantially to mortality rates. Accidents, which cover a broad range of unintentional injuries, also represent a major cause of death, particularly in younger populations. Finally, stroke is a critical condition leading to high mortality, correlating with risk factors such as hypertension and diabetes. Together, these causes represent the most significant threats to adult life and align closely with statistical data regarding mortality rates.

In contrast, the other options include a mix of conditions that may not accurately represent the top five killers across all adult populations. For instance, while liver disease and renal failure are important health issues, they do not rank as highly in overall mortality statistics compared to the selections in the correct response.
