C) a canaliculi.
D) a lamellae.

Accepted Answer

The basic structural unit of compact bone is the osteon. The osteon is also known as the Haversian system and is composed of concentric rings of bone tissue called lamellae surrounding a central canal containing blood vessels and nerves. Lacunae and canaliculi are small spaces and channels within the bone tissue that house bone cells, while lamellae are the concentric rings that make up the osteon.
