Solution

The correct option is A Dichogamy
Herkogamy is shown by hermaphroditic angiosperms to reduce sexual interference between anthers and female stigma function. Autogamy, or self-fertilization, refers to the fusion of two gametes that come from one individual. cleistogamy is self-fertilization that occurs within a permanently closed flower. Dichogamy means when stamens and stigma mature at different times favouring cross-pollination.

So, 'the correct option is 'Dichogamy'
