Explanation

The correct answer is Dichogamy. Dichogamy refers to a condition in bisexual flowers where the male reproductive organs androecium and female reproductive organs gynaecium mature at different times. This is a strategy used by plants to prevent self pollination and encourage cross pollination. There are two types of dichogamy: protandry, where the androecium matures first, and protogyny, where the gynaecium matures first. In contrast, Herkogamy refers to physical barriers between organs, Heterogamy refers to having different types of flowers on the same plant, and Monogamy is not a botanical term related to floral maturation.
