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.
A hypothesis......Plz mark brainliest
The most specific would be felis catus. That is the name of the species in biology, and there are no more taxonomic divides after species.
