Answer 1

The correct option is A Dichogamy

Continous self-pollination or inbreeding leads to inbreeding depression, a condition where the decrease in genetic vigor and vitality results in reduced fitness in offsprings.
Dichogamy is the condition in some flowering plants where the pistils and stamens mature at different times, thus preventing self-pollination.
