B. Incisors
C. Premolars
D. Molars

Explanation

**Step-by-Step Solution:**

1. **Understanding the Types of Teeth**:
- There are different types of teeth in humans, each serving a specific function. The main types are incisors, canines, premolars, and molars.

2. **Identifying the Function of Each Type**:

- **Premolars**: These teeth are broader and designed for crushing and grinding food. They do not have a cutting function.
- **Molars**: These are the largest teeth with a flat surface, primarily used for grinding food. Adults usually have 12 molars.

3. **Analyzing the Options**:
- **Option A (Canine)**: Incorrect, as canines are not used for cutting.
- **Option B (Incisor)**: Correct, as incisors have a chisel-like structure that helps in cutting and biting food.
- **Option C (Premolars)**: Incorrect, as premolars are used for crushing, not cutting.
- **Option D (Molars)**: Incorrect, as molars are used for grinding food.

4. **Conclusion**:
- The teeth that have chisel-like structures which help in cutting and biting food are the **incisors**.

**Final Answer**: The correct answer is **B. Incisors**.
