D. Posterior

Answer

To solve the question "Which part of thyroid cartilage in larynx is closed?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Larynx**:
- The larynx is an important structure in the respiratory system that houses the vocal cords. It is made up of various cartilages, one of which is the thyroid cartilage.

2. **Identify the Thyroid Cartilage**:
- The thyroid cartilage is the largest cartilage of the larynx and forms the bulk of the front wall. It is shaped like a shield and is more prominent in males, often referred to as the "Adam's apple".

3. **Determine the Orientation of the Thyroid Cartilage**:
- The thyroid cartilage has both a dorsal (back) and a ventral (front) aspect. The ventral side faces the front of the neck, while the dorsal side faces the back.

4. **Identify the Closed Part**:
- The question asks which part of the thyroid cartilage is closed. In anatomical terms, the ventral side of the thyroid cartilage is closed, as it forms a protective barrier in front of the larynx and houses the vocal cords behind it.

5. **Select the Correct Option**:
- Based on the understanding that the ventral side of the thyroid cartilage is the part that is closed, we can conclude that the answer is "ventral".

### Final Answer:
The part of the thyroid cartilage in the larynx that is closed is the **ventral** part.
