In the experiment conducted to test why individuals in the tree species Fuschsia excorticata retain flowers after they turn red even though the trees pollinate and offer a nectar reward only when flowers are green (Figure attached 10.28  first tested the 'pollinator-attraction' hypothesis that red flowers attract pollinators:  once drawn to a tree, pollinators could forage on the green flowers still present, increasing overall pollination efficiency.  Please assess the lowercase-Roman-numeral-labelled statements that appear immediately below and click the uppercase-letter-labelled response that appears below and conveys the most accurate  information.

Because a Kotukutuku flower hangs downward, its ovary is at the top (Figure
10.28a). The body of the bell consists of the hypanthium, or floral tube, and the
sepals. The style resembles an elongated clapper. It is surrounded by shorter sta-
mens and a set of reduced petals.
The hypanthium and sepals are the most conspicuously showy parts of the
flower. They remain green for about 5.5 days after the flower opens, then begin
to turn red (Figure 10.28b). The transition from green to red lasts about 1.5 days,
