Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R):

Assertion (A): A flower is defined as modified shoot wherein the shoot apical meristem changes to floral meristem.

Reason (R): Internode of the shoot gets condensed to produce different floral appendages laterally at successive nodes instead of leaves.

In the light of the above statements, choose the correct answer from the options given below:

In the ABC model of floral organ determination in Arabidopsis, the expression of class Agenes alone determines the development of sepals, expression of class A genes along with class B genes determines petal formation, expression of class B genes along with class C genes determines the formation of stamens and expression of class genes alone determines carpel formation. Loss of class B gene function would result in flowers with whorls in the following order (from outer whorl to inner whorl)
