Papaya, date palm prevent
1 Autogamy but not geitonogamy as they are dioceous
2 Geitonogamy but not autogamy as they are dioceous
3 Both autogamy and geitonogamy as they are dioceous
4 Neither autogamy nor geitonogamy as they are dioceous
Explanation:
In several species such as papaya, male and female flowers are present on different plants, that is each plant is either male or female (dioecy). This condition prevents both autogamy and geitonogamy.
