D. If both Assertion and Reason are false.

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that the red color of flowers attracts butterflies and wasps but not bees. This indicates a difference in how these insects perceive colors.

2. **Understanding the Reason**: The reason provided is that bees are not sensitive to the color red. This suggests that bees have a limited color perception compared to butterflies and wasps.

3. **Analyzing Flower Structure**: A typical flower consists of four whorls: calyx, corolla, androecium, and gynoecium. The corolla, which is made up of petals, is often colorful to attract pollinators.

4. **Role of Color in Pollination**: The vibrant colors of petals are crucial for attracting insects, which increases the chances of pollination. Pollination is essential for the transfer of pollen grains from the male anther to the female stigma, leading to fertilization.

5. **Color Perception in Insects**: Butterflies and wasps can perceive the color red, while bees cannot. This is due to the differences in their photoreceptors. Bees are color-blind to red and can only see colors up to the range of orange and yellow.

6. **Evaluating the Assertion and Reason**: Both the assertion and the reason are true. The assertion correctly identifies that red flowers attract certain insects while not attracting bees, and the reason accurately explains why bees do not respond to red.

7. **Conclusion**: Since both the assertion and reason are true, and the reason provides a correct explanation for the assertion, the answer is that both statements are true and the reason is the correct explanation for the assertion.

**Final Answer**: Both assertion and reason are true, and the reason is the correct explanation for the assertion.
