✓ Correct answer: C. EnamelEnamel is the highly mineralised surface of the crown, providing resistance against mechanical and chemical damage.
Why the other options are incorrect:
• Dentine: Dentine lies beneath enamel and is not the outermost surface.
• Pulp chamber: The pulp chamber is a deep internal compartment.
• Cementum: Cementum coats the root, not the crown.
• Periodontal ligament: The periodontal ligament suspends the tooth within its bony socket.
