Which motor skill group involves large muscle or major muscle groups, such as a straight punch or forward baton strike?

The correct answer is associated with activities that rely on the engagement of large muscle groups, which is characteristic of gross motor skills. These skills involve movements that require the use of larger muscle groups to perform tasks that demand strength, coordination, and balance. A straight punch or forward baton strike exemplifies gross motor skills, as these actions necessitate significant bodily movement and coordination of various muscle groups, such as the arms, shoulders, and legs.

In contrast, fine motor skills pertain to tasks that involve smaller, more precise movements often involving the fingers and hands, like writing or buttoning a shirt. Complex motor skills may refer to tasks that involve a combination of both gross and fine motor skills but do not specifically pertain to large muscle movements alone. Therefore, understanding the distinction between these types of motor skills clarifies why the option regarding gross motor skills is the most applicable in this context.
