b. 30 minutes

c. 60 minutes

d. 90 minutes

e. 3 hours

The Institute of Medicine of the National Academy of Sciences recommends that people accumulate 60 minutes of moderate-intensity physical activity most days of the week.

Explanation:

Physical activity guidelines for adults were originally formed for the opposition to morbidity and fatality. Although 30 min of regular physical exercise may stop unhealthy weight accumulation in some people, it is now commonly stated that this extent of physical activity may be inadequate for the opposition of the age-related weight gain in several if not most adults.  

For most lazy people, this would necessitate computing more than 60 min of physical exercise to their daily habit. In common, similar to about 60 to 90 min of regular leisure-time physical exercise, it is suggested to limit age-related weight gain.
