Assertion :-Flower is a modified shoot.
Reason :-In flower vegtation shoot apical meristem changes to reproductive shoot apex/floral meristem in which internodes do not elongate and the axis gets condensed.

Options

A. If both Assertion & Reason are True & Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are false.

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Assertion**: The assertion states that "Flower is a modified shoot." This is correct because flowers develop from the shoot apical meristem, which is responsible for the growth of the plant's stem and leaves.

2. **Understanding the Reason**: The reason provided is that "In flower vegetation, the shoot apical meristem changes to reproductive shoot apex/floral meristem in which internodes do not elongate and the axis gets condensed." This is also correct. During flower development, the shoot apical meristem transitions into a floral meristem.

3. **Analyzing the Characteristics of Floral Meristem**: In the floral meristem, the internodes (the segments of the stem between the nodes) do not elongate as they do in vegetative growth. Instead, the axis becomes condensed, leading to the formation of flowers in a compact arrangement.

4. **Conclusion**: Both the assertion and the reason are true, and the reason accurately explains the assertion. Therefore, the correct option is that both the assertion and reason are true, and the reason is the correct explanation for the assertion.
