(b) Hind limb
(c) Scapula
(d) Clavicle

Options

A. Fore limb
B. Hind limb
C. Scapula
D. Clavicle

Answer

To solve the question regarding the presence of astragalus and calcaneum, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Bones**: Understand that astragalus and calcaneum are specific types of bones. They are referred to as crurotarsal bones.

2. **Understand Their Classification**: Recognize that these bones are classified as proximal tarsal bones. Tarsal bones are part of the skeletal system that forms the ankle and foot.

3. **Locate Their Position**: Determine where these bones are found in the body. The astragalus and calcaneum are primarily associated with the hind limb.

4. **Review the Structure of the Hind Limb**: The hind limb consists of several bones, including:
- Femur (thigh bone)
- Tibia and Fibula (lower leg bones)
- Tarsals (including astragalus and calcaneum)
- Metatarsals
- Phalanges (toes)

5. **Conclude the Answer**: Since both astragalus and calcaneum are part of the tarsal bones, and tarsal bones are located in the hind limb, the correct answer to the question is (b) Hind limb.

### Final Answer:
(b) Hind limb
