B. vitreous humour
C. skin
D. all of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Hyaluronic Acid**:
- Hyaluronic acid is classified as a heteropolysaccharide, which means it is composed of different types of monosaccharides. Specifically, it contains acetylglucosamine and glucuronic acid.

2. **Function of Hyaluronic Acid**:
- It acts as a cementing material in the body. This means it helps to hold cells together and provides structural support to various tissues.

3. **Distribution in the Body**:
- Hyaluronic acid is widely distributed throughout the body, particularly in connective tissues, epithelial tissues, and neural tissues. This distribution is crucial for its role in lubrication and hydration.

4. **Specific Locations**:
- Hyaluronic acid is found in several specific areas of the body, including:
- Skin: It helps maintain moisture and elasticity.
- Eyes: It is present in the vitreous humor, which is the gel-like substance in the eye that helps maintain its shape.
- Ovum: It plays a role in reproductive processes.
- Synovial fluid: It acts as a lubricant in joints, reducing friction during movement.

5. **Conclusion**:
- Given the information about the presence and function of hyaluronic acid, we can conclude that it is found in all the mentioned areas: skin, eyes, ovum, and synovial fluid. Therefore, the answer to the question is that hyaluronic acid is found in all of the above.

**Final Answer**: All of the above (skin, eyes, ovum, synovial fluid).
