Skin is

Options

A. Cuboidal epithelium
B. Stratified epithelium
C. Columnar epithelium
D. Pseudostratified epithelium.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the type of tissue that makes up the skin. We need to analyze the given options to determine which one is correct.

2. **Evaluating the Options**:
- **Option 1: Cuboidal Epithelium**: This type of epithelium is found in specific locations such as the surface of ovaries, lining of nephrons, and thyroid glands. It is not related to the skin.
- **Option 2: Stratified Epithelium**: This is also known as stratified squamous epithelium. It is the correct type of tissue that forms the skin, providing protection against mechanical and chemical damage and preventing water loss.
- **Option 3: Columnar Epithelium**: This type of epithelium is found in the lining of the fallopian tubes and parts of the respiratory system. It does not make up the skin.
- **Option 4: Pseudostratified Epithelium**: This epithelium is primarily found in the respiratory tract, such as the lining of the trachea. It is not involved in forming the skin.

3. **Identifying the Correct Answer**: After evaluating all the options, we find that option 2, stratified epithelium (stratified squamous epithelium), is the correct answer as it constitutes the skin.

4. **Conclusion**: The skin is made up of stratified epithelium, which serves protective functions and helps in preventing water loss.
