a. more adults reported leading an inactive lifestyle and living with obesity when compared to other risk factors.
b. obesity and high blood pressure share the same risk for developing heart disease.
c. smoking cigarettes is the only risk factor that stems from an unhealthy lifestyle choice.
d. diabetes affects so few adults in the u.s. that it is not a risk factor for heart disease.

Explanation:

• Option A: The bar for "Inactive Lifestyle" and "Obesity" are among the tallest, meaning a higher percentage of adults have these risk factors compared to others like smoking, high cholesterol, or diabetes. This matches the chart.
• Option B: The bars for "Obesity" and "High Blood Pressure" are different heights, so their risks aren't the same. Eliminate B.
• Option C: Inactive lifestyle and obesity also stem from unhealthy lifestyle choices, so smoking isn't the only one. Eliminate C.
• Option D: The chart shows diabetes is a risk factor (even if the percentage is low), so it is a risk factor. Eliminate D.

Answer:

A. More adults reported leading an inactive lifestyle and living with obesity when compared to other risk factors.
