The correct option is B Complete, bisexual and hypogynous
The flower is complete (all four whorls such as calyx, corolla, androecium and gynoecium) are present.
The flower is bisexual as it has both the male reproductive whorl (androecium represented by stamens) and the female reproductive whorl (gynoecium represented by the carpel).
It is hypogynous with a superior ovary as all the floral whorls are below the ovary (gynoecium) and the ovary is described as superior.
An incomplete flower is one in which at least one of the whorls is missing. For example, when the flowers are unisexual, they are said to be incomplete or when the flowers are naked with both the calyx and corolla absent, they are said to be incomplete.
Epigynous is when the ovary is inferior and all the whorls such as the calyx, corolla and the androecium arise from above the ovary.
