Ferulic acid, coumarin and hesperidin are

Options

A. Secondary plant products
B. Hormones
C. Enzymes
D. Vitamins.

Answer

**Step-by-Step Solution:**

1. **Identify the Compounds**: The question mentions three compounds: Ferulic acid, Coumarin, and Hesperidin.

2. **Understand the Classification**: These compounds are classified as secondary metabolites in plants. Secondary metabolites are organic compounds that are not directly involved in the normal growth, development, or reproduction of an organism.

3. **Define Secondary Metabolites**: Secondary metabolites serve various functions in plants, such as defense against herbivores, protection against pathogens, and attraction of pollinators. They are crucial for the plant's survival but are not essential for basic metabolic processes.

4. **Categorize the Compounds**: Secondary metabolites can be divided into three main groups:
- **Flavonoids**: A class of secondary metabolites that includes compounds like Hesperidin.
- **Phenolic Compounds**: This group includes compounds like Ferulic acid and Coumarin.
- **Polyphenolic Compounds**: These are complex compounds that include various phenolic structures.

5. **Conclusion**: Based on the classification and characteristics of the mentioned compounds, the correct answer to the question is that Ferulic acid, Coumarin, and Hesperidin are examples of secondary plant products.

**Final Answer**: Ferulic acid, Coumarin, and Hesperidin are secondary plant products.
