The abundantly and widely distributed tissues in higher animals are  

Options

A. muscular
B. epithelial
C. nervous
D. connective

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the type of tissue that is abundantly and widely distributed in higher animals.

2. **Identifying the Options**: The options provided are:
- Muscular Tissue
- Epithelial Tissue
- Nervous Tissue
- Connective Tissue

3. **Analyzing Each Tissue Type**:
- **Muscular Tissue**: This tissue is responsible for movement and is composed of cells that can contract. However, it is not the most widely distributed tissue in the body.
- **Epithelial Tissue**: This tissue forms protective layers on internal and external surfaces of the body. While important, it does not cover the entire body as extensively as connective tissue.
- **Nervous Tissue**: Found in the brain, spinal cord, and nerves, this tissue is crucial for coordination and control of body activities but is not as widely distributed as connective tissue.
- **Connective Tissue**: This is the most abundant and widely distributed tissue in higher animals. It connects different tissues and organs, providing support and structure. It includes various types such as cartilage, bone, adipose (fat), and blood.

4. **Conclusion**: After analyzing all options, the correct answer is **Connective Tissue** as it is the most abundantly and widely distributed tissue in higher animals.
