Answer» A. white fibres and some yellow elastic fibres
Explanation: A ligament is composed of dense fibrous bundles of collagenous fibres and spindle-shaped cells known as fibrocytes, with little ground substance. Ligaments may be of two major types: white ligament is rich in coilagenous fibres, which are sturdy and inelastic; and yellow ligament is rich in elastic fibres, which are quite tough even though they allow elastic movement.
