Correct answer: D

The correct answer is :

Option D : Both A and R are true and R is the correct explanation of A

Explanation :

Statement A is true. A flower is indeed a modified shoot wherein the shoot apical meristem changes to a floral meristem.

Statement R is also true. In the process of flower formation, the internodes of the shoot get condensed, and instead of leaves, different floral appendages (such as sepals, petals, stamens, and carpels) are produced laterally at successive nodes.

Moreover, Statement R is indeed the correct explanation for Statement A. The transition from the shoot apical meristem to the floral meristem involves the condensation of internodes and the lateral production of floral appendages at nodes, which leads to the formation of a flower.
