The correct answer is D. Throwing softballs at targets
Step-by-step explanation:
Moderate to vigorous exercise or physical activities include activities that increase breathing and heart rate and often require movement and effort. For example, jogging, walking vigorously or playing some sport. This implies from the options given jogging the track, playing 3-on-3 basketball or playing touch football are all moderate to vigorous exercise activities. However, in the case of throwing softballs at targets, this is not a moderate to vigorous exercise because it does not imply an effort that leads to a considerable increase in the breathing or heart rate and therefore, this activity is the least likely to help accomplish the goal of 60 minutes of moderate to vigorous exercise.
