• B. sexual reproduction
• C. vegetative propagation
• D. apomixis

Answer 1

The correct option is D apomixis

Apomixis is the phenomenon that leads to the formation of the embryo wherein parts of the sexual apparatus are used but without fertilisation. It is a special mechanism to produce seeds without fertilisation.
Fertilisation is also absent in vegetative propagation but parts of the sexual apparatus are not involved.
A fertilised ovary is called fruit. The process of producing fruit without fertilisation of ovules is called parthenocarpy. Fruits like seedless banana, figs, watermelon, etc are very common examples of parthenocarpic fruits that horticulturists prefer to grow.
