The correct option is
A CocosAnemophily or wind pollination is a form of pollination whereby pollen is distributed by wind.
Almost all gymnosperms are anemophilous, as are many plants in the order Poales, including grasses, sedges and rushes. Other common anemophilous plants are oaks, coconut, sweet chestnuts, alders and members of the family Juglandaceae
The defining characteristic of the genus
Salvia is the unusual pollination mechanism. When a pollinator probes a male stage flower for nectar, (pushing the posterior anther theca) the lever causes the stamens to move and the pollen to be deposited on the pollinator. When the pollinator withdraws from the flower, the lever returns the stamens to their original position. Whereas, birds are the pollinators in bottle brush (
Callistemon). Cross pollination occurs in
Vallisneria.
Thus, the correct answer is option A.
