Correct option is B
· Carrot (Protandry): Carrot flowers exhibit protandry, where anthers mature before the stigma, promoting cross-pollination.
· Radish (Sporophytic self-incompatibility): Radish exhibits sporophytic self-incompatibility, which prevents self-fertilization.
· Brinjal (Heteromorphic flower): Brinjal exhibits heteromorphic flowers, meaning there are variations in floral structure to promote cross-pollination.
· Papaya (Dioecy): Papaya plants exhibit dioecy, meaning separate male and female plants exist, ensuring cross-pollination.
