Final answer:
Option (C), The coupling where the thumb pad and finger pads oppose each other near the tips is known as a Tip grip, enabled by the thumb's range of motion for fine motor skills.
Step-by-step explanation:
The type of coupling described in the question, where the thumb pad and the pads of three or four fingers oppose each other near the tips (and the object grasped does not touch the palm), is known as a Tip grip. In opposition, the thumb moves to make contact with the tips of the fingers, which is important for fine motor skills, such as picking up small objects. This movement is enabled by the specialized anatomy of the hand where the first metacarpal bone provides the thumb a range of motion independent from the other fingers.
