Hint: A dioecious plant in which either male (stamens) or female (gynoecium) reproductive structure is present in the flowers.
Step by step answer:In higher plants, there are very well-developed sex organs. There is also a clear distinction between the male and the female sex organs. The reproductive structures of the Angiospermic plants are known as the flowering plants. The male sex organs of a flower are known as the stamen. It consists of an anther and a filament. The female sex organs of a flower are known as the carpel or the pistil. The carpel consists of the style, stigma, and ovary. The ovary further contains the ovule. If a plant has unisexual flowers, then it is classified as Monoecious or Dioecious plant, based on the position of the flowers.
Monoecious – When the male flower and the female flower are present on the same plant body, then it is known as the monoecious plant. Examples – Cucurbits, Maize, Coconut, etc.
Dioecious – When the male and the female flowers are present on the different plant bodies, then it is known as the dioecious plant. Examples – Date palm, Papaya, etc.
Hence, based on the definition of the dioecious plants, they have either male or female flowers on the plant.
Thus, the correct answer is option (B)
Additional Information:
The terms monoecious and dioecious are different from the unisexual and bisexual.
Unisexual – If the male sex organ i.e., the stamen and the female sex organ, i.e., the carpel, occur on different flowers, then, it is known as unisexual flower. These kinds of flowers undergo cross-pollination for fertilization. Example – Papaya, Mulberry, Watermelon, etc.
Bisexual – If the male sex organ i.e., the stamen and the female sex organ, i.e., the carpel, occur on the same flower, then, it is known as a bisexual flower. These kinds of flowers undergo self-pollination for fertilization. Example – China Rose, Rose, Mustard, etc.
Note: The two different conditions are monoecious (male flower and the female flower are present on the same plant body) while in dioecious (male and the female flowers are present on the different plant bodies).
