Answer:
D
Solution:
Cleistogamous flowers mean anther and stigma present close each other in the closed flower. They are bisexual which cannot open even at maturity and thus self-pollination occurs. For this reason these type of flowers are invariably autogamous. Cleistogamous flowers undergo self-pollination only, which reduces the chances of variation and evolution of genetically superior progeny.
