Select the wrong match

Options

A. Epiphyseal plate - Hyaline fibrous cartilage
B. Intervertebral disc - White fibrous cartiage
C. Pinna - Elastic cartilage
D. Xiphisternum - Elastic cartilage

Answer

To determine the wrong match from the given options, we need to analyze each option carefully based on the type of cartilage associated with each structure.

### Step-by-Step Solution:

1. **Option 1: Epiphyseal Plate - Hyaline Fibrous Cartilage**
- The epiphyseal plate is located at the ends of long bones and is crucial for bone growth. It is primarily made up of **hyaline cartilage**, not fibrous cartilage. Therefore, this option is incorrect as it mentions "hyaline fibrous cartilage," which is a misnomer. The correct term should be just **hyaline cartilage**.

2. **Option 2: Intervertebral Disc - White Fibrous Cartilage**
- The intervertebral discs are located between adjacent vertebrae and are composed of **fibrocartilage** (a type of white fibrous cartilage). This option is correct.

3. **Option 3: Pinna - Elastic Cartilage**
- The pinna (outer ear) is indeed made up of **elastic cartilage**, which provides flexibility and shape. This option is correct.

4. **Option 4: Xiphoid Sternum - Elastic Cartilage**
- The xiphoid process is the lowest part of the sternum and is primarily made up of **hyaline cartilage** during development. It does not consist of elastic cartilage. Therefore, this option is incorrect as it states "elastic cartilage."

### Conclusion:
The wrong matches are:
- **Option 1: Epiphyseal Plate - Hyaline Fibrous Cartilage** (should be just hyaline cartilage)
- **Option 4: Xiphoid Sternum - Elastic Cartilage** (should be hyaline cartilage)

The correct answer to the question is **Option 4: Xiphoid Sternum - Elastic Cartilage**.
