The minimum recommended duration of moderate-intensity exercise per week for adults is indeed 150 minutes. This guideline is supported by health organizations such as the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC). Engaging in at least 150 minutes of moderate-intensity aerobic activity helps improve cardiovascular fitness, build endurance, and reduce the risk of chronic diseases such as obesity, diabetes, and heart disease.

Moderate-intensity exercise is defined as activities that raise the heart rate and breathing but still allow for conversation, such as brisk walking or cycling on flat terrain. By meeting the 150-minute guideline, individuals are more likely to achieve health benefits that enhance overall well-being and quality of life.

The other choices represent different amounts of exercise that could be beneficial but do not align with the established minimum recommended duration for significant health benefits. For example, while 75 minutes of vigorous-intensity exercise can also provide health benefits, it doesn't meet the minimum for moderate-intensity activity. Likewise, 300 minutes or more may be beneficial for additional health gains but exceeds the baseline recommendation. Finally, 90 minutes is less than the recommended amount and would not sufficiently meet the health guidelines for moderate-intensity exercise.
