Which of these food ingredients is not obtained from either plants or animals?

Options

A. Salt
B. Honey
C. Milk
D. Wheat

Explanation

To determine which food ingredient is not obtained from either plants or animals, we can analyze each option provided.

### Step-by-Step Solution:

1. **Identify the Ingredients**: We have four ingredients to consider: salt, honey, milk, and wheat.

2. **Examine Salt**:
- Salt is not derived from plants or animals. It is primarily obtained from seawater through evaporation or from mining rock salt. Therefore, salt does not have a plant or animal origin.

3. **Examine Honey**:
- Honey is produced by honey bees, which collect nectar from flowers (plants). Hence, honey is of plant and animal origin.

4. **Examine Milk**:
- Milk is obtained from cows, which are animals. Thus, milk is of animal origin.

5. **Examine Wheat**:
- Wheat is a cereal grain that comes from plants. Therefore, wheat is of plant origin.

6. **Conclusion**:
- Among the four ingredients, salt is the only one that is not obtained from either plants or animals. The other three (honey, milk, and wheat) are derived from either plants or animals.

### Final Answer:
- The food ingredient that is not obtained from either plants or animals is **salt**.
