Rattlesnake fern, or Botrychium virginianum, as shown below, is a species of fern, a seedless plant, that is found all across North America. Which structure is involved in the reproduction of this plant?

A. spores

B. pollen

C. cones

D. fruit

I think rhe answer is: A. spores

The correct answer should be A. spores

Ferns don't have seeds and they reproduce using spores. Cones have seeds in them and seeds fall out. Pollen enters a flower and then the flower becomes a fruit. This is sexual reproduction of plants. Since ferns don't have this, they have to reproduce with spores.
