Correct answer: A — Fibroblasts
Fibroblasts are the most abundant cell type in the PDL and are the primary producers of collagen (Types I and III) and other extracellular matrix components. They are responsible for continuous turnover (simultaneous synthesis and degradation) of the PDL collagen fibres, which is essential for tooth eruption, orthodontic tooth movement, and adaptation to functional demands.
