Ligament is

Options

A. Dense irregular connective tissue
B. Loose connective tissue
C. Specialised connective tissue
D. Dense regular connective tissue

Answer

### Step-by-Step Solution

1. **Understanding Connective Tissue**:
- Connective tissue is the most abundant and widely distributed type of tissue in the animal body. Its main function is to link organs together and provide support.

2. **Categories of Connective Tissue**:
- Connective tissues can be divided into three main categories:
- Loose connective tissues
- Dense connective tissues
- Specialized connective tissues

3. **Identifying Loose Connective Tissue**:
- Loose connective tissues have a semi-fluid ground substance with cells and fibers (like structural proteins) that are loosely arranged. Examples include areolar tissue and adipose tissue.
- Since ligaments do not fit this description, they are not classified as loose connective tissue.

4. **Identifying Dense Connective Tissue**:
- Dense connective tissues contain many fibers of structural proteins such as collagen and elastin, providing more strength and flexibility compared to loose connective tissues.
- Dense connective tissue is further divided into:
- **Dense Regular Connective Tissue**: Fibers are arranged in parallel bundles.
- **Dense Irregular Connective Tissue**: Fibers are not arranged in a parallel fashion.

5. **Classifying Ligament**:
- Ligaments are structures that connect one bone to another. They consist of dense regular connective tissue because they have parallel bundles of structural proteins that provide strength and stability.
- Therefore, ligaments fall under the category of dense regular connective tissue.

6. **Conclusion**:
- Based on the classification, the correct answer is that a ligament is a type of **dense regular connective tissue**.
