Question

1. when done correctly, physical activity can decrease the risk of

cardiovascular diseases.
mental health.
allergies.
isolation.
clear all

Explanation:

Physical activity is known to improve cardiovascular health by strengthening the heart, improving blood circulation, and reducing factors like high blood pressure and cholesterol, which are linked to cardiovascular diseases. Mental health is positively impacted (but the option says "mental health" as a risk to decrease, which is less accurate in phrasing; physical activity improves mental health rather than decreasing its "risk" in the same way). Allergies are related to immune responses and not directly affected by physical activity. Isolation is a social/mental state, and while physical activity can help with social interaction, it's not a direct risk reduction like cardiovascular diseases. So the correct option is the one about cardiovascular diseases.

Answer:

A. cardiovascular diseases
