Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R :
Assertion A : The shoot apical meristem transforms into the floral meristem, giving rise to a flower, a modified shoot.
Reason R : The condensed internodes of the shoot give rise to various floral appendages laterally at successive nodes, replacing leaves.

Both A and R are true and R is the correct explanation of A
Both A and R are true but R is NOT the correct explanation of A
