Assertion: UV rays are carcinogenic in nature.
Reason: It stimulates the growth of cancer.

Options

A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
B. If both Assertion and Reason are true and the Reason is not the correct explanation of the Assertion.
C. If Assertion is true but the Reason is false.
D. If both Assertion and Reason are false.

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that "UV rays are carcinogenic in nature." To evaluate this, we need to define what "carcinogenic" means. Carcinogenic substances are those that can cause cancer in living tissue.

2. **Evaluating the Nature of UV Rays**: Ultraviolet (UV) rays are a type of non-ionizing radiation. While they can cause skin damage and increase the risk of skin cancer, they are not classified as carcinogenic in the same way that ionizing radiation (like X-rays and gamma rays) is. Ionizing radiation can directly damage DNA, leading to cancer.

3. **Understanding the Reason**: The reason states that "it stimulates the growth of cancer." This implies that UV rays actively promote cancer growth. While UV rays can lead to mutations and increase the risk of skin cancer, they do not directly stimulate cancer growth in the same manner as carcinogenic agents do.

4. **Conclusion on Both Statements**: Since UV rays are not classified as carcinogenic in the same way that ionizing radiation is, the assertion is false. Additionally, while UV rays can lead to skin cancer, they do not directly stimulate cancer growth, making the reason false as well.

5. **Final Evaluation**: Both the assertion and the reason are false. Therefore, the correct answer is that both statements are incorrect.
