Which bones are formed by intramembranous ossification?
Long bones arms and legs
Bones of the pelvic girdle

Flat bones of the skull
The Correct Answer is D
Intramembranous ossification is a process of bone formation in which bone tissue forms directly within mesenchymal (undifferentiated) connective tissue membranes. This process is responsible for the formation of the flat bones of the skull, including the frontal, parietal, occipital, and temporal bones.
Long bones of the arms and legs, bones of the pelvic girdle, and vertebrae are formed by endochondral ossification, a different process of bone formation in which bone tissue replaces hyaline cartilage.
