Answer:
a. Multiple gene duplication events have led to the production of a paralogous multigene family.
Explanation:
A globin gene family consists of several clusters of related genes formed by duplication of an ancestral gene. The different variants of venom proteins coded by closely related genes can reply this ancestral gene, forming this way a globin gene family in Cone snails.
