The tissue covering the external surface of animal and internal surface of visceral organs is

Options

A. Adipose tissue
B. Connective tissue
C. Cartilaginous tissue
D. Epithelial tissue.

Answer

To answer the question regarding the tissue that covers the external surface of animals and the internal surface of visceral organs, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Types of Tissues**: The question provides four options: adipose tissue, connective tissue, cartilaginous tissue, and epithelial tissue. We need to analyze each option to determine which one fits the description.

2. **Analyze Epithelial Tissue**: Epithelial tissue is characterized by its role in covering surfaces. It forms the outer layer of the skin (external surface) and lines various organs and cavities (internal surfaces). This includes the lining of the digestive tract, respiratory tract, and reproductive organs.

3. **Consider Connective Tissue**: Connective tissue serves to support, bind, and protect other tissues and organs. It includes various types such as adipose tissue and cartilage, but it does not primarily cover surfaces.

4. **Examine Cartilaginous Tissue**: Cartilaginous tissue is a type of connective tissue that provides support and flexibility, particularly at joints. It does not cover surfaces like the skin or internal organs.

5. **Look at Adipose Tissue**: Adipose tissue is specialized connective tissue that stores fat. While it is found throughout the body, it does not serve as a covering for surfaces.

6. **Conclusion**: Based on the analysis, the tissue that covers the external surface of animals and the internal surface of visceral organs is **epithelial tissue**.

### Final Answer:
The correct answer is **epithelial tissue**.
