According to current WHO physical activity guidelines cited in national NCD prevention strategy, adults aged 18 to 64 years should accumulate at least:

• A 150 to 300 minutes of moderate-intensity aerobic activity per week ✓
• B 75 minutes of moderate-intensity aerobic activity per week
• C 300 minutes of vigorous-intensity activity daily
• D 60 minutes of any physical activity per week

Explanation

WHO recommends 150 to 300 minutes of moderate-intensity aerobic physical activity per week, or 75 to 150 minutes of vigorous-intensity activity, or an equivalent combination, plus muscle-strengthening activities on two or more days per week. Option B reverses the thresholds: 75 minutes per week applies to vigorous, not moderate, intensity. Daily vigorous activity of 300 minutes exceeds recommendations, and 60 minutes per week is far below the minimum effective dose.
