The correct answer is: Autogamy, but not geitonogamy
Autogamy but not geitnogamy : Unisexuality promotes or favours the cross pollination (xenogamy) and prevent self pollination (Autogamy). Geitnogamy involve transfer of pollen grain between two flowers of the same plant so unisexuality will not prevent geitnogamy.
