Answer:
Osteons are cylindrical structures that contain a mineral matrix and living osteocytes connected by canaliculi, which transport blood. They are aligned parallel to the long axis of the bone. Each osteon consists of lamellae, which are layers of the compact matrix that surround a central canal called the Haversian canal.
Participants share the same home environment but do not share the same genetic code so researchers can study the impact of biological factors. Thus, option "B" is correct.
