Solution

The correct option is C Assertion is correct but Reason is incorrect.
Cleistogamy promotes self-pollination. It describes the trait of certain plants to propagate by using non-opening, self-pollinating flowers. Cross pollinated flowers are usually unisexual and will need the help of a pollinator for the pollination process to take place. Whereas if the flowers are bisexual, which means both sexes are present on the same flower, there are more chances of cross pollination to take place.
