Answer:
The correct option is formation of bone from within fibrous membranes.
Explanation:
The process of intramembranous ossification results in the production of bones from the fibrous membranes. The mesenchymal cells get differentiated into different kinds of osteoblasts. The process of intramembranous ossification occurs in the skull. In other parts where bones are to be formed by this process, the mesenchymal cells get converted into cartilage first. The cartilage will then be converted or replaced into bones.
Bones at the base of the skull and the long bones are produced by endochondral ossification.
