Assertion : Originwise hair are epithelial tissue which are of ectodermal origin.
Reason : Epithelial tissue can be formed from mesoderm and endoderm also.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are false.

Answer

To solve the assertion and reason question, we will analyze both statements step by step.

### Step 1: Analyze the Assertion
The assertion states: "Origin-wise, hair are epithelial tissue which are of ectodermal origin."

- **Explanation**: Hair is indeed a type of epithelial tissue. It originates from the epidermis, which is the outermost layer of the skin. The epidermis is derived from the ectoderm, one of the three primary germ layers formed during embryonic development. Therefore, this assertion is true.

### Step 2: Analyze the Reason
The reason states: "Epithelial tissue can be formed from mesoderm and endoderm also."

- **Explanation**: Epithelial tissue can indeed arise from all three germ layers: ectoderm, mesoderm, and endoderm. For example, the endoderm gives rise to the epithelial lining of the gastrointestinal tract, while the mesoderm contributes to the epithelial tissues in various organs. Thus, this reason is also true.

### Step 3: Determine the Relationship
Now we need to determine if the reason correctly explains the assertion.

- **Explanation**: While both statements are true, the reason does not specifically explain why hair is of ectodermal origin. The assertion specifically refers to hair, while the reason discusses epithelial tissue in general. Therefore, the reason is not the correct explanation for the assertion.

### Conclusion
Both the assertion and reason are true, but the reason does not correctly explain the assertion.

The correct answer is: **Both assertion and reason are true, but reason is not the correct explanation of assertion.**
