D

Detailed explanation-1: -Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae. Small channels (canaliculi) radiate from the lacunae to the osteonic (haversian) canal to provide passageways through the hard matrix.

Detailed explanation-2: -Spongy (Cancellous) Bone. Like compact bone, spongy bone, also known as cancellous bone, contains osteocytes housed in lacunae, but they are not arranged in concentric circles.

Detailed explanation-3: -Lacuna in anatomy Biology definition: (histology) Lacuna is the small cavity containing an osteocyte in bone, or a chondrocyte in cartilage; (botany) an air space in plant tissues; (general) a small depression, empty space, or cavity.
