Explanation:

Analyze CDC physical activity recommendations for children and adults

The CDC recommends that children and adolescents aged 6–17 years do 60 minutes (1 hour) or more of moderate-to-vigorous physical activity daily, including aerobic, muscle-strengthening, and bone-strengthening activities. For adults, the recommendation is at least 150 minutes of moderate-intensity aerobic activity per week, plus muscle-strengthening activities on 2 or more days.

Evaluate the given options against guidelines

• Option A describes a comprehensive plan: "Family hikes for 60 minutes twice a week, a family bike ride for 60 minutes once a week, and a muscle-strengthening activity like an obstacle course at the park twice a week." This plan incorporates both aerobic and muscle-strengthening activities suitable for both children and adults.
• Options B, C, and D describe single, less comprehensive activities (e.g., a walk around the neighborhood, an hour of swimming, or a structured exercise class) that do not fully address the multi-component weekly recommendations (aerobic plus muscle-strengthening) for both age groups as effectively as Option A.

Select the best aligned plan

Option A is the most comprehensive weekly plan that aligns with the CDC's multi-component recommendations for both children and adults.
