Adult supervision is crucial in both structured and unstructured play to ensure the safety of children. Structured play involves planned activities with rules, while unstructured play is spontaneous and free-flowing. Both types of activities carry risks of injuries without supervision.
- Option (a): Structured play requires supervision but is not the only type.
- Option (b): Unstructured play also requires monitoring.
- Option (d): Video games do not involve physical activities.
Thus, option (c) “For both structured and unstructured play” is correct.
