Which bone is part of the axial skeleton?

Explanation:
The idea being tested is how bones are categorized into the axial versus the appendicular skeleton. The vertebral column is the central axis of the skeleton, forming the core along which the body stands and moves, and it is a defining part of the axial skeleton. Each vertebrae stack to protect the spinal cord and support the head, making them a foundational component of the body's central structure. The femur and radius are long bones of the limbs, which belong to the appendicular skeleton that supports movement and attaches the limbs to the trunk. The pelvis is the pelvic girdle that connects the lower limbs to the trunk and is considered part of the appendicular skeleton as well. So, among these options, vertebrae fit the axial skeleton.
