Final answer:
Janine using her whole hand to point is an example of gross motor skills, which involve larger movements, unlike fine motor skills that require more precision.
Step-by-step explanation:
Infant Janine is using her whole hand to "point" at her favorite toy, and her actions are best explained by gross motor skills. Gross motor skills focus on large muscle groups and involve larger movements, such as balancing or running, while fine motor skills involve smaller movements requiring more precision, like using scissors to cut paper. Since Janine is using her whole hand, a movement involving a larger muscle group, it falls under gross motor skills rather than the precision movements associated with fine motor skills.
