Weakest, the most common and strongest cartilages respectively are  

Options

A. Hyaline & fibrous cartilages
B. elastic & fibrous cartilage
C. elastic & hyaline
D. fibrous & elastic cartilage

Answer

To solve the question regarding the weakest, most common, and strongest cartilages, we need to identify the types of cartilage and their characteristics. Here’s a step-by-step breakdown:

### Step 1: Understand the Types of Cartilage
Cartilage is a type of connective tissue found throughout the body. There are three main types of cartilage:
1. **Hyaline Cartilage**
2. **Elastic Cartilage**
3. **Fibrous Cartilage**

### Step 2: Identify the Characteristics of Each Type
- **Hyaline Cartilage**: This is the most common type of cartilage. It is found in areas such as the nose, trachea, and at the ends of long bones. It provides support with some flexibility.

- **Elastic Cartilage**: This type contains more elastic fibers, making it flexible and resilient. It is found in structures like the ear and epiglottis. However, it is not the strongest type of cartilage.

- **Fibrous Cartilage**: This is the strongest type of cartilage due to its dense collagen fibers. It is found in areas that require tough support, such as intervertebral discs and the pubic symphysis.

### Step 3: Determine Weakest, Most Common, and Strongest Cartilages
- **Weakest Cartilage**: Elastic Cartilage (due to its flexibility and lower tensile strength).
- **Most Common Cartilage**: Hyaline Cartilage (it is the most prevalent type in the body).
- **Strongest Cartilage**: Fibrous Cartilage (due to its dense collagen fibers).

### Conclusion
Based on the analysis:
- Weakest cartilage: **Elastic Cartilage**
- Most common cartilage: **Hyaline Cartilage**
- Strongest cartilage: **Fibrous Cartilage**

### Final Answer
The weakest, most common, and strongest cartilages respectively are:
- **Elastic Cartilage**, **Hyaline Cartilage**, **Fibrous Cartilage**.
