D.

Correct option is C

The correct answer is (C)  They shed off except sepal which may be persistent in some plants

  • ​Fertilization initiates various changes in the flower, with the ovary developing into fruit, ovules becoming seeds, and the zygote turning into an embryo.
  • The non-essential parts like sepals, petals, stamens, style, and stigma fall off after their reproductive roles are fulfilled.

Information booster:

  • Sepals, Petals, and Stamens: After fertilization, the sepals, petals, and stamens typically fall off the flower. These parts are no longer needed for the plant's reproduction process.
  • Ovary and Fruit Formation: The ovary, which is the base of the pistil, remains attached to the plant. It develops into a fruit, which will protect the seeds as they grow.
  • Ovules and Seeds: The ovules inside the ovary transform into seeds. These seeds will eventually grow into new plants.
  • Zygote Development: The zygote formed after fertilization divides and develops into an embryo within the seed.
  • Sepals After Fertilization: In some cases, the sepals may stay attached to the fruit and either dry up or shrink.
  • Petals, Stamens, Style, and Stigma: The petals, stamens, style, and stigma fall off the flower after fertilization because they have completed their role in attracting pollinators and facilitating fertilization.​
