What is the correct sequence of development from a functional megaspore in angiosperms?

If the functional megaspore fails to develop normally, which of the following structures would be directly affected?

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.

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

The development of a flower from a modified shoot involves the transformation of the:

(a) Axillary bud into floral meristem

(b) Shoot apical meristem into floral meristem

(c) Leaf primordia into floral appendages

(d) Internodes into floral organs
