D. internal ear

Answer

To determine where Volkman's canals occur, we will analyze each of the options provided: bone, cartilage, liver, and internal ear.

### Step-by-Step Solution:

1. **Understanding Volkman's Canals**:
- Volkman's canals, also known as perforating canals, are channels in the bone that allow for the passage of blood vessels and nerves. They connect the Haversian canals (central canals) of the bone.

2. **Analyzing the Options**:
- **Internal Ear**:
- The internal ear contains structures like the cochlea, which is involved in hearing. It does not have any canals like Volkman's canals.
- **Conclusion**: This option is incorrect.

- **Liver**:
- The liver has a structure known as the hepatic duct, which is involved in bile transport. It does not contain Volkman's canals.
- **Conclusion**: This option is incorrect.

- **Cartilage**:
- Cartilage is a flexible connective tissue that does not contain blood vessels or canals. It relies on diffusion for nutrient supply and waste removal.
- **Conclusion**: This option is incorrect.

- **Bone**:
- Bones are structured with various canals, including Haversian canals and Volkman's canals. Volkman's canals are specifically responsible for connecting blood vessels and nerves between Haversian systems.
- **Conclusion**: This option is correct.

3. **Final Answer**:
- Volkman's canals occur in **bone**.
