Which is the most important factor for continuity of a species from an evolutionary point of view?

The correct option is A

Replication of genetic material

Replication of genetic material is the most important factor for continuity of a species from an evolutionary point of view. Only when genetic material replicates, it could be transferred from one generation to the next, resulting in continuity of a species. Asexual animals do not produce gametes while sexual animals do and yet, replication of genetic material takes place in both asexual as well as sexual animals. Synthesis of proteins does not play any role in continuity of species.
