The correct option is B Haversian canal
Haversian canals can be defined as a series of tubes around narrow channels formed by lamellae. This region of bone is called as cortical bone. Osteons are arranged in parallel to the long axis of the bone. The Haversian canals surround blood vessels and nerve cells throughout the bone and they communicate with osteocytes in lacunae through canaliculi. This unique arrangement is conducive to mineral salt deposits and storage, which gives the bone tissue its strength.
