Solution

The correct option is A
Actinomorphic, hypogynous with twisted aestivation

The flowers of China rose are actinomorphic i.e. the flower can be divided into two equal halves by any vertical plane; hypogynous i.e. the ovary develops at the top of the convex/conical thalamus; twisted aestivation i.e. the margin of one petal overlaps the margin of the adjacent one.
