The correct option is A A, B, C All
Pollination is an essential part of plant reproduction. Pollen from a flower's anthers (the male part of the plant) drops onto a pollinator. The pollinator then take this pollen to another flower, where the pollen sticks to the stigma (the female part). The fertilized flower later yields fruit and seeds.
Wind, water, and animals, primarily insects and birds, effect pollen transfer in flowering plants (angiosperm). There is a wide range of animal pollinators of angiosperms as well as a wide range of adaptations by the flowers to attract those pollinators.
So, the correct answer is "option D"
