Question

The hardest part of the teeth is:

• A. dentine
• B. enamel
• C. pulp cavity
• D. canine

Hint:

Enamel is the hardest substance in the human body—harder than bone.

Answer 1

The Correct Option is B

Step 1: Fact.
Enamel is a highly mineralised layer (mainly hydroxyapatite) covering the crown of the tooth.
Step 2: Comparison.
Dentine lies below enamel and is softer; pulp cavity contains nerves and blood vessels; canine is a type of tooth, not a tissue.
Step 3: Conclusion.
Therefore, enamel is the hardest part of the tooth.
