In human fibrous cartilage is found abundantly

Options

A. (a) Hyaline cartilage of joints
B. (b) Nostrils
C. (c) Intervertebral discs
D. (d) External ear

Answer

**Step-by-Step Solution:**

1. **Understanding Fibrous Cartilage**: Fibrous cartilage, also known as fibrocartilage, is a type of cartilage that is densely packed with collagen fibers. This composition gives it strength and the ability to withstand pressure.

2. **Identifying Locations of Fibrous Cartilage**: In humans, fibrous cartilage is found in specific locations where support and flexibility are required. Notably, it is abundantly present in the pubic symphysis and intervertebral discs.

3. **Analyzing the Options**:
- **Option A: Hyaline cartilage of joints**: This option is incorrect because hyaline cartilage, not fibrous cartilage, is found in joints.
- **Option B: Nostrils**: This option is also incorrect as nostrils contain hyaline cartilage.
- **Option C: Intervertebral disc**: This is the correct answer since intervertebral discs are made up of fibrous cartilage, providing cushioning between the vertebrae.
- **Option D: External ear**: This option is incorrect because the external ear is made of elastic cartilage, not fibrous cartilage.

4. **Conclusion**: Based on the analysis, the correct answer is Option C: Intervertebral disc, as it is the location where fibrous cartilage is abundantly found in humans.
