The Correct Option is B
Solution and Explanation
Parthenogenesis is the process of development of seeds from unfertilised female gametes. Seeds may be haploid or diploid (Gk. parthenos-virgin, genesisdescent). It is the development of a new individual from a single gamete without fusion with another gamete. In lower plants both the types of gametes can undergo parthenogenesis but in higher plants, usually the female gametes shows this facility.

Sexual Reproduction in Flowering Plants
Sexual reproduction in flowering plants takes place or happens when the production of a new organism occurs from two parents by making use of their gametes or sex cells. Both sexual and asexual reproduction can be found in plants. Nearly all flowering plants reproduce sexually. Flowers play a captious role in the process as it carries both the male and female reproductive parts commonly known as androecium and gynoecium respectively.
An individual flower comprises the following parts -
- Pedicle
- Calyx
- Petals
- Sepals
- Stamen
- Pistil
- Receptacle
