C. cuneiform
D. corniculate

Answer

**Step-by-Step Solution:**

1. **Understanding Unpaired Cartilages**: In the human body, there are several types of cartilages. Among them, some are paired (two of each) and some are unpaired (one of each).

2. **Identifying Unpaired Cartilages**: The unpaired cartilages in the human body include:
- Epiglottis
- Thyroid cartilage
- Cricoid cartilage

3. **Analyzing the Options**: The question provides four options, and we need to identify which of these is an unpaired cartilage.
- **Option 1: Arytenoid** - This is a paired cartilage, shaped like a pyramid, found in the larynx and involved in sound production. Thus, it is not the answer.
- **Option 2: Thyroid** - This is an unpaired cartilage, making it a potential answer.
- **Option 3: Cuneiform** - This cartilage is paired and consists of two small elongated structures, so it is not the answer.
- **Option 4: Corniculate** - This is also a paired cartilage involved in the relaxation of vocal cords, so it is not the answer.

4. **Conclusion**: After analyzing all the options, the only unpaired cartilage listed is the Thyroid cartilage, which corresponds to option 2.

**Final Answer**: The unpaired cartilage is the Thyroid cartilage (Option 2).
