Answer:
A) The male stamens hold the pollen, the female pistil holds the ovule, and the petals attract pollinators.
Stamens (male reproductive parts of a flower) collectively forms the male reproductive organ (androecium) in a flower whereas pistil (the female reproductive part of a flower) forms the female reproductive organ called gynoecium.
Stamen consists two parts that are anther (that produces pollens, male reproductive cells) and a stalk like structure called filament, which supports/ holds pollen producing anther.
The female pistil holds the ovule that is enclosed by ovary in flowering plants (angiosperms) and the petals in a flower attract pollinators.
Thus, option A) is the right answer.
