Solution

The correct option is B apogamy
Apogamy is the development of a plant embryo without fertilisation.

Apospory is the formation of a diploid gametophyte directly from a sporophyte without meiosis.

Parthenocarpy is the formation of fruits without fertilisation. The fruits are seedless.

Parthenogenesis is the formation of an organism from an ovum without fertilisation and is seen in some invertebrates.
