The correct answer is: fine motor development.

Explanation:

Motor development refers to the physical development of a child, and as such includes all movements varying from basic movements (moving fingers, ankles, grabbing etc.) to more advanced (running, skipping, jumping...).

Basic movements refer to fine motor skills such as grabbing, holding something, writing and picking something up, while advanced refer to gross motor skills which involve running, jumping and coordinating.

With that being said, Melanie is involved in fine motor development as she can skillfully use fork and a spoon - movements that include grabbing and holding something.
