Answer 1

Answer: (C)

A cartilage cell is present in a fluid filled space, the cartilage lacuna. Matrix essentially consists of water, proteoglycans (proteins and carbohydrates), some lipids, collagen, noncollagenous protein and collagen fibres. Mature cells are larger in size, more rounded, but still have a few surface projections and are known as chondrocytes. The free surfaces of hyaline cartilage are covered by a fibrous membrane called the perichondrium but it is not present in fibrous cartilage
