✓ Correct answer: B. Dentine Dentine makes up the majority of the tooth structure and is positioned immediately beneath the enamel. Why the other options are incorrect: • Pulp chamber: The pulp chamber is located deeper within the tooth, not immediately beneath the enamel. • Cementum: Cementum covers the root surface and is not found beneath the enamel. • Gingival tissue: The gingiva is external soft tissue surrounding the tooth, not a layer beneath enamel. • Alveolar bone: Bone supports the tooth socket but is not situated beneath the enamel layer.
