• B. Both assertion and reason are true but reason is not the correct explanation of assertion.
• C. The assertion is true but reason is false.
• D. Both assertion and reason are false.

Answer 1

The correct option is C The assertion is true but reason is false.

Cleistogamous flowers are bisexual flowers which do not open at all. Therefore they never expose the anthers and stigma.

Cleistogamous flowers produce assured seed-set even in the absence of pollinators. This is because the anther and stigma lie close to each other. When pollen is released, it comes in contact with the stigma resulting in pollination. Hence, pollinators are not required for pollination in cleistogamous flowers.
