(c) 80
(d) 37

Options

A. 128
B. 120
C. 80
D. 37

Answer

To determine the total number of bones in the appendicular skeleton of a rabbit, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Skeleton**: The skeleton of mammals is divided into two main parts: the axial skeleton and the appendicular skeleton. The axial skeleton includes the skull, vertebral column, ribs, and sternum, while the appendicular skeleton consists of the limbs and their attachments.

2. **Identify the Bones in the Axial Skeleton**: In rabbits, the axial skeleton is composed of 132 bones. This includes the bones of the skull, vertebrae, ribs, and sternum.

3. **Focus on the Appendicular Skeleton**: The appendicular skeleton is primarily made up of the bones of the limbs (forelimbs and hindlimbs) and their girdles (shoulder and pelvic girdles).

4. **Determine the Number of Bones in the Appendicular Skeleton**: For rabbits, the appendicular skeleton contains approximately 128 bones. This is a characteristic number for rabbits and is different from that of humans, which has 126 bones in the appendicular skeleton.

5. **Select the Correct Option**: Given the options provided:
- (a) 128
- (b) 120
- (c) 80
- (d) 37

The correct answer is (a) 128.

### Final Answer:
The total number of bones in the appendicular skeleton of a rabbit is **128**.
