Hint: The arrangement of stamen and petals are different in different types of flowering plants. In some flowers stamens are attached to the anther, in some conditions stamens are fused together, and in some conditions stamens are attached to the perianth accordingly the flowers are classified.
Complete Answer:
- The flower part consists of sepals, the green leaf-like part of the flower. It involves the protection of flowers when it is in bud form. Petals are the coloured part of the flower that attracts the pollinators towards itself.
- Stamen is found inside the petals made of filaments and anther. The anther produces pollen grains that carry the male gametes, therefore the stamens is the male reproductive part. Carpel is found in the centre of the plant that is in flask shape. It is divided into stigma, style, and ovary.
- The pollen grains from the stigma fall on the carpel, and from the style tube it reaches to the ovary for fertilization of the egg for reproduction.
- In other words we can say that the flowers consist of four whorls; calyx, corolla that is composed of petals, androecium that contain the stamen, and the gynoecium that consists of one or more carpels. Depending on the arrangement of these four whorls the flowers are classified further.
- Now, epipetalous are the flowers in which androecium is attached with the flower petals, therefore, epipetalous is the conditions of stamens. For example, Datura metel shows epipetalous condition.
Thus, the correct option is ‘B’ Stamen.
Note: In some of the flowers like lily sepals and petals are the same therefore they are considered as perianth. When in flowers the anther is attached to the perianth it is considered as epiphyllous. And in diadelphous condition the stamens are fused together and arranged in two different bundles, like in Papilionaceae.
