Answer: A
When the androecium and gynoecium of a bisexual flower mature at different times, the condition is dichogamy.
It prevents self-pollination and so promotes outbreeding. Where the anthers mature first it is protandry; where the stigma does, protogyny. Herkogamy achieves the same end by physical separation instead.
