The Correct option is A

Explanation with High Yield Facts :

• Classification of Cementum Based on the Nature and Origin of Collagen Fibres.
• Organic matrix derived form 2 sources: Periodontal ligament (Sharpey’s fibres), Cementoblasts
• Extrinsic fibres derived from PDL. These are in the same direction of the PDL principal fibres i.e. perpendicular or oblique to the root surface.
• Intrinsic fibres derived from cementoblasts. Run parallel to the root surface and at right angles to the extrinsic fibres

• The area where both extrinsic and intrinsic fibres meet is called mixed fibre cementum.
