Solution

The correct option is D self-pollinated
Cleistogamous flowers are self-pollinated flowers. These flowers are bisexual and never open. The anther and stigma lie close to one another. Pollen released by anther reaches the stigma without any pollinating agent.

Cleistogamous flowers are invariably autogamous as there is no chance of cross-pollination in them.
