To determine which bone is not a carpal bone from the provided options, we need to identify each bone's classification:

1. Caphoid: This appears to be a misspelling of "scaphoid," which is a carpal bone.
2. Hamate: This is a carpal bone located in the wrist.
3. Navicular: In the context of the wrist, this would typically refer to the scaphoid. However, the navicular bone is also known as the scaphoid of the wrist, so it is also a carpal bone.
4. Pisiform: This is a carpal bone and is one of the proximal row carpal bones.
5. Trapezium: This is also a carpal bone located in the wrist.

Final Answer

The correct answer is navicular, as it is sometimes considered a term for the scaphoid and can lead to confusion. However, if referring strictly to typical carpal alignment, "navicular" may not be recognized as a distinct carpal bone separate from the scaphoid. Hence, the safest choice is "navicular" as it is often less emphasized in the structure of carpal bones in teaching.
