D. Suberin

Answer

To answer the question "Chemical present in the walls of cork cell is," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking for the specific chemical that is found in the walls of cork cells.

2. **Identify the Options**: The options provided are:
- A) Lichenin
- B) Chitin
- C) Cutin
- D) Subarin

3. **Analyze Each Option**:
- **Cutin**: This is a waxy substance found in the cuticle of plants, not specifically in cork cells. Therefore, it is not the correct answer.
- **Lichenin**: This is an organic polymer found in the cell walls of sclerenchyma and tracheal elements, but not in cork cells. Thus, it is also incorrect.
- **Chitin**: This is a complex polysaccharide found in the cell walls of fungi. It does not pertain to cork cells, making it incorrect as well.
- **Subarin**: This is an inert, waxy substance that is specifically found in the walls of cork cells. It is known for its impermeability and is the correct answer.
