Correct option is
A

Can reproduce freely with each other and form seeds

Species refers to the basic unit of biological classification and a taxonomic rank, it defines a group of potentially interbreeding natural populations and can be reproductively isolated from other similar groups. While a molecular marker would have given a clearer distinction, this works out as a useful formulation that shows the impact of sexual reproduction on the dynamics of natural selection.
Therefore, the correct answer is option A.
