Answer 1

Answer: (A)

Enamel

Enamel, the first layer of tooth that is visible in the mouth, is a porous , calcified substance made from crystalline calcium phosphate. Enamel appears to be a soft beige to white color, yet it is semi-translucent allowing the color of the dentine layer to penetrate through. Enamel is also the hardest substance of the body.

So, the correct option is 'Enamel'.
