Answer: (C)

Verified step by step guidance

1. Step 1: Begin by understanding the structure of a tooth. Teeth are composed of several distinct tissue materials, each serving a specific function. These include enamel, dentin, pulp, and cementum.
2. Step 2: Enamel is the hard, outermost layer of the tooth, primarily composed of hydroxyapatite, a crystalline calcium phosphate. It provides protection against wear and decay.
3. Step 3: Dentin lies beneath the enamel and is a calcified tissue that makes up the bulk of the tooth. It is less hard than enamel and contains microscopic tubules that can transmit sensations to the pulp.
4. Step 4: Pulp is the innermost part of the tooth, containing blood vessels, nerves, and connective tissue. It plays a vital role in nourishing the tooth and providing sensory feedback.
5. Step 5: Cartilage is not a component of teeth. It is a flexible connective tissue found in areas such as joints, the nose, and the ear. This makes cartilage the correct answer as the material not found in teeth.
