Select the mismatch.

Options

A. Scapula - Situated in between `2^(nd)` to `7^(th)` ribs
B. Ball and socket joint - Humerous and pectoral girdle
C. Rib cage - Formed by vertebrae,ribs and stemum
D. Pelvic girdle - Aarticulates with thigh bone at public symphysis

Answer

To solve the question of selecting the mismatch, we will analyze each option one by one to determine if they are correctly matched.

### Step-by-Step Solution:

1. **Analyze Option 1: Scapula**
- The scapula is a large triangular bone located in the dorsal part of the upper thorax.
- It is indeed situated between the second to seventh ribs.
- **Conclusion**: This is a correct match.

2. **Analyze Option 2: Ball and Socket Joint (Humerus and Pectoral Girdle)**
- A ball and socket joint allows for a wide range of motion.
- The head of the humerus fits into the glenoid cavity of the scapula (part of the pectoral girdle).
- **Conclusion**: This is a correct match.

3. **Analyze Option 3: Rib Cage Formation**
- The rib cage is formed by 12 thoracic vertebrae, 12 pairs of ribs, and the sternum.
- This statement is accurate.
- **Conclusion**: This is a correct match.

4. **Analyze Option 4: Pelvic Girdle Articulation**
- The pelvic girdle articulates with the thigh bone (femur) at the acetabulum, not at the pubic symphysis.
- The pubic symphysis is a joint between the two pubic bones of the pelvic girdle.
- **Conclusion**: This is a mismatch.

### Final Answer:
The mismatch is in **Option 4**: "Pelvic girdle articulates with thigh bone at pubic symphysis."
