The correct option is B Feathery stigmas
The
phenomenon of pollen grains being transferred to stigma by air is called
anemophily. In anemophily, wind is the abiotic agent of pollination. This is
the more common amongst abiotic pollinations. The pollen grains are light and
non-sticky, so that they can easily be carried by air currents. The flowers
have well-exposed stamens, so that the pollens are easily dispersed into wind
currents. Anemophilous flowers have large feathery stigma to easily trap the
air borne pollen grains. Anemophily is quite common in grasses, maize, wheat,
sugarcane, bamboo, etc.
