उत्तर

Autogamy can occur in a chasmogamous flower if both pollen and ovules mature simultaneously.

Explanation:

Autogamy in chasmogamous flowers occurs when pollen and ovules mature at the same time, allowing pollen to fertilize ovules within the same flower. Without simultaneous maturity, self-pollination is unlikely in open flowers like chasmogamous ones.
