Answer:

C. Contains chondrocytes located in lacunae

Chondrocytes in lacunae are the only cells that make up the cartilage. They secrete the cartilage matrix and are kind of embedded in them. Cartilage matrix is made mainly of proteoglycans and collagen. Chondrocyte is round or polygonal in shape. More the number of chondrocytes, bendier the cartilage.
