Solution
The correct option is A A - Chondrin; B - Chondrocyte; C - Lacuna; D - Capsular matrix; E - Perichondrium Chondrin is bluish white gelatin-like substance, that forms the matrix of the cartilage. So, here, labeling 'A' is chondrin. The cells in hyaline cartilage are contained in cavities in the matrix, called lacunae. So, here, labeling 'C' is lacuna. Chondrocytes are the only cells found in healthy cartilage. So, here labeling 'B' is chondrocyte. The capsular matrix is a thin zone of the matrix that surrounds each lacuna. So, here labeling 'D' is a capsular matrix. The perichondrium is a layer of dense irregular connective tissue that surrounds the cartilage of the developing bone. So, labeling 'E' is perichondrium.
