Enamel is 2 times stronger than the tooth
B
Correct answer
Explanation
The statement is false - tooth enamel is actually much stronger than the tooth itself. Enamel is the hardest substance in the human body, consisting of 96% minerals. It protects the softer dentin and pulp inside the tooth. Saying it's only '2 times stronger' is an understatement - it's significantly harder.
