Step 1: The slide shows large, irregular, dense bundles of collagen fibres in the matrix with rows of chondrocytes lying between them. This is the hallmark of fibrocartilage.
Step 2: Fibrocartilage has alternating layers of cartilage matrix and thick dense layers of type I collagen fibres. It is found in intervertebral discs, the pubic symphysis and menisci, where it resists compression and tension.
Step 3: Why the others are wrong. Hyaline cartilage has a glassy homogeneous matrix with no visible coarse fibres. Articular cartilage is a specialised hyaline cartilage. Elastic cartilage shows a network of elastic fibres in the matrix.
