the unmineralized organic component of bone.
A
osteoid
B
trabeculae
C
calcitonin
D
vitamin
Explanation: 

Detailed explanation-1: -In histology, osteoid is the unmineralized, organic portion of the bone matrix that forms prior to the maturation of bone tissue. Osteoblasts begin the process of forming bone tissue by secreting the osteoid as several specific proteins.

Detailed explanation-2: -Organic Components:-The organic component of the bone matrix is called osteoid.-It contains proteoglycans, glycoproteins and collagen fibers.-Without the organic components of the matrix, the bone would be very brittle and it would break if twisted or stretched.

Detailed explanation-3: -Osteoid is an unmineralized organic tissue that eventually undergoes calcification and is deposited as lamellae or layers in the bone matrix. From: Research Methods in Human Skeletal Biology, 2013.

Detailed explanation-4: -Bone is composed of various types of cells and collagenous extracellular organic matrix, which is predominantly type I collagen (85–95%) called osteoid that becomes mineralised by the deposition of calcium hydroxyapatite.

Detailed explanation-5: -Osteoblast cells secrete unmineralised organic bone matrix called osteoid.
