To find the minimum time period for cardiorespiratory benefit from exercise, we can refer to expert recommendations. One reliable source is the American Heart Association (AHA), which provides guidelines on physical activity for improving cardiovascular health.

To find their recommended minimum duration, we can visit the AHA's website or search for their physical activity guidelines online.

Upon visiting the AHA's website, we can find that their recommended minimum time period for cardiorespiratory benefit from exercise is 150 minutes of moderate-intensity aerobic activity, or 75 minutes of vigorous-intensity aerobic activity, per week. This recommendation is based on the CDC's Physical Activity Guidelines for Americans.

Given the choices provided, none of them match the recommended duration of 150 minutes or 75 minutes per week. Therefore, none of the options A, B, C, or D accurately represent the expert consensus on the minimum time period for cardiorespiratory benefit from exercise.
