A dicotyledonous plant bears flowers but never produces fruits and see...
Fruits can develop from a single ovary of a single flower(simple fruit) or from several free carpels of a single flower (aggregate) or form whole inflorescence(multiple). In total, fruits develop from ovaries. This is why, a dioecious plant (unisexual) bearing only staminate (male) flowers will not produce fruits, whereas monoecious plants (bisexual) or dioecious plants bearing only pistillate (female) lowers or pistillate and staminate both can bear fruits. So, the correct answer is 'Plant is dioecious and bears only staminate flowers'.

Understanding Plant Sexual Reproduction
In flowering plants, the production of fruits and seeds is closely linked to the types of flowers they possess. The scenario described involves a dicotyledonous plant that fails to produce fruits and seeds despite bearing flowers.
Key Factors Affecting Fruit and Seed Production
- Types of Flowers: The plant's ability to produce fruits and seeds is determined by the presence of reproductive structures in its flowers.
- Staminate vs. Pistillate Flowers:
- Staminate Flowers: These flowers contain only male reproductive organs (stamens) and do not produce ovules or fruit.
- Pistillate Flowers: These contain female reproductive organs (pistils) and can develop into fruits if fertilized.
Why Option D is Correct
- Dioecious Plants: These plants have male and female reproductive structures on separate individuals.
- Presence of Only Staminate Flowers: If the plant in question is dioecious and only produces staminate (male) flowers, it lacks the female pistils necessary for fertilization. Consequently:
- No Fertilization Occurs: Without female flowers, there can be no fertilization of ovules.
- Absence of Fruits and Seeds: As a result, the plant will not produce fruits or seeds, explaining the observed phenomenon.
Conclusion
The most probable cause for a dicotyledonous plant bearing flowers but failing to produce fruits and seeds is that it is dioecious and bears only staminate flowers. This situation highlights the importance of both male and female reproductive structures in the reproductive success of flowering plants.
