D. saal wood

Answer

To solve the question of which type of wood does not contain vessels, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks which type of wood lacks xylem vessels. Xylem vessels are essential for water transport in plants.

2. **Analyze the Options**: The options provided are:
- (a) Teak wood
- (b) Shisham wood
- (c) Chir wood
- (d) Saal wood

3. **Evaluate Each Option**:
- **Teak Wood**: Teak wood is known to have xylem vessels. Therefore, it cannot be the correct answer.
- **Shisham Wood**: Shisham wood also contains xylem vessels. Thus, it is not the correct answer.
- **Chir Wood**: Chir wood belongs to the pine family. In this type of wood, the xylem is composed only of tracheids, and it lacks vessels entirely. This makes it a potential correct answer.
- **Saal Wood**: Saal wood, like teak and shisham, contains xylem vessels. Hence, it is not the correct answer.

4. **Conclusion**: Based on the analysis, the only wood type that does not contain vessels is Chir wood (option c).

### Final Answer:
(c) Chir wood
