Which definition describes immobility of the index, middle, ring, and little finger?

Explanation:
The concept here is describing a hand impairment pattern by which four fingers are unable to move while the thumb remains functional. When the index, middle, ring, and little fingers are immobile, it indicates a loss of motion across those digits (typically due to intrinsic hand muscle weakness or fixed contractures at the finger joints), whereas the thumb is still able to move. This pattern specifically points to the immobility of the four fingers, not the thumb, wrist, or elbow. That makes the description of immobility of the index, middle, ring, and little finger the correct definition.
