Vedclass · Answer

(A) Cleistogamous flowers are those that do not open at all. In these flowers,the anthers and stigma lie close to each other. When anthers dehisce in the flower buds,pollen grains come in contact with the stigma to effect pollination. Thus,cleistogamous flowers produce assured seed-set even in the absence of pollinators. Since the flowers remain closed,there is no chance of cross-pollination,and they always exhibit autogamy. Therefore,option $A$ is the correct statement.
