Which statement correctly describes the repair of hyaline cartilage?

The repair of hyaline cartilage is limited by its lack of blood vessels, nerves, and lymphatics. That avascular environment means the tissue can’t bring in many reparative cells or nutrients after injury, so the body fills the defect with fibrocartilage rather than regenerating the original hyaline cartilage. Fibrocartilage has a different makeup, with more collagen type I and less proteoglycan, which makes it mechanically weaker and less able to withstand joint loading over time. So the repair tissue ends up being fibrocartilage, leading to a weaker structure than the native hyaline cartilage. The other statements don’t fit because hyaline cartilage is not innervated, it does not heal rapidly without intervention, and the repair tissue does not remain hyaline and strong.
