The correct option is B Many ovules in each ovary
Plants that show wind pollination (anemophily) have well-exposed stamens and produce light and non-sticky pollen grains so that they can be easily transported by the wind currents.
The stigmas are large and feathery to easily trap air-borne pollen grains.
Flowers which are pollinated by wind often have a single ovule in the ovary and numerous flowers are packed into an inflorescence.
Hence, the statement in option b is incorrect.
