B

`{:(P_(1),P_(2),P_(3)),("Autogamy","Xenogmay","Geitonogamy"):}`

Text Solution

Verified by Experts

The correct Answer is:
C

Autogamy (GK. Autos-self, gamos-marriage) is a type of self pollination in which an intersexual or perfect flowers is pollinated by its own pollen. Geitonogamy (GK. Geiton-neighbour, gamos-marriage) is a type of pollination in which pollen grains of one flower are transferred to the stigma of another flower belonging to either the same plant or genetically similar plant. In geitonogamy, the flowers often show modifications similar to ones found in xenogamy or cross pollination. Xenogamy (GK. xenos-strange, gamos-marriage) or cross pollination is the transfer of pollen grains from anther of one flower to the stigma of a genetically different flower.
