B)stroma
C)lamellae
D)chromosome
E)lacunae

Accepted Answer

The basic structural unit of compact bone tissue is the osteon, also known as the Haversian system. It consists of concentric layers of bone tissue called lamellae surrounding a central canal called the Haversian canal. The lamellae contain osteocytes housed in small spaces called lacunae, while the Haversian canals contain blood vessels and nerves.
