Solution

The correct option is D Both Assertion and Reason are incorrect.
Insect pollinated flowers are large, conspicuous, bright coloured and have pleasant smell. They have nectarines on receptacles or on spurs at the base of flower whorls and produce nectar. Nectar is a sweet substance that attracts insects towards the flowers. The rough and sticky pollens are stuck on the bodies of visiting insects and are transferred to sticky stigma of other flower. Attraction of insects towards flowers facilitates cross pollination. This makes Reason an incorrect statement. Insects visit flowers for nectar; only honeybee forms honey out of nectar. This makes Assertion incorrect.
Thus, the correct answer is option D.
