Following statements are regarding to the molecular basis of the coincidence model in Arabidopsis.
A.
In Arabidopsis under short days, there is little overlap between CO mRNA
expression and daylight.
B.
CO protein does not accumulate to sufficient levels in the phloem to promote
the expression of the transmissible floral stimulus and the plant remains vegetative.
C. Under long days, the peak of CO mRNA abundance (at hours 12 through 16) overlaps with daylight (sensed by phyA and cryptochrome [cry]), allowing CO protein to accumulate.
D. CO activates FLC mRNA expression in the phloem, which
causes flowering when the FT protein is translocated to the apical meristem.

According to the ABC model of flower development in Arabidopsis, three classes of organ identity genes— designated A, B, and C— are required to specify the identity of floral organs in each whorl of a flower. If wild type Arabidopsis were transformed with a chimeric gene composed of a C class promoter fused to a B class coding sequence, which of the following arrangements (outer to inner) would be predicted?
